Market Dominance of GCash in the Philippine Digital Payment Ecosystem: A Secondary Data Analysis (ICPSR 309020)

Released/updated on: 2026-08-12

Geographic coverage: Philippines

Time period: 2013-01-01--2025-12-31

Abstract

The rapid expansion of digital payment systems has transformed financial transactions in the Philippines, with mobile wallet platforms becoming central to everyday economic activities. This study examines the market dominance of GCash within the Philippine digital payment ecosystem using a secondary data analysis approach. Data were synthesized from official statistics, industry reports, and fintech market analyses to examine trends in digital payment adoption, mobile wallet usage, merchant integration, and market growth. Findings indicate an increase in digital payment adoption, with the share of digital retail payments rising from approximately 1% in 2013 to 57.4% in 2024. Concurrently, GCash experienced user expansion, growing from 20 million registered users in 2019 to more than 81 million in 2023, alongside a merchant network exceeding 2.5 million partners nationwide. Comparative analysis also shows that GCash maintains the most comprehensive service ecosystem among Philippine e-wallet platforms, contributing to its widespread adoption among consumers and small businesses. The results suggest that platform accessibility, trust, convenience, and network effects contribute to the platform’s dominant position. This study provides empirical insight into the structural and behavioral factors shaping digital payment adoption in the Philippines and highlights the role of fintech platforms in supporting the country’s expanding digital economy.

The New Immigrant Survey Round 1 (NIS-2003-1), United States, 2003-2004 [Public and Restricted-Use Version 1] (ICPSR 38031)

Released/updated on: 2025-08-25

Geographic coverage: United States

Time period: 2003-01-01--2004-12-31

The New Immigrant Survey (NIS) was a nationally representative, longitudinal study of new legal immigrants to the United States and their children. The sampling frame was based on the electronic administrative records compiled for new legal permanent residents (LPRs) by the U.S. government (via, formerly, the U.S. Immigration and Naturalization Service (INS) and now its successor agencies, the U.S. Citizenship and Immigration Services (USCIS) and the Office of Immigration Statistics (OIS)). The sample was drawn from new legal immigrants during May through November of 2003. The geographic sampling design took advantage of the natural clustering of immigrants. It included all top 85 Metropolitan Statistical Areas (MSAs) and all top 38 counties, plus a random sample of MSAs and counties. The baseline survey was conducted from June 2003 to June 2004 and yielded data on:

8,573 Adult Sample respondents,
810 sponsor-parents of the Sampled Child,
4,915 spouses,
and 1,072 children aged 8-12.

Interviews were conducted in the respondents' language of choice. The Round 1 questionnaire items that were used in social-demographic-migration surveys around the world as well as the major U.S. longitudinal surveys were reviewed in order to achieve comparability. The NIS content includes the following information: demographic, health and insurance, migration history, living conditions, transfers, employment history, income, assets, social networks, religion, housing environment, and child assessment tests.

Primary Care Audit Study for 10 States in the United States, 2012-2013, 2014 & 2016 (ICPSR 36785)

Released/updated on: 2018-10-10

Geographic coverage: Oregon, Montana, Iowa, United States, Illinois, Texas, Massachusetts, Georgia, Arkansas, New Jersey, Pennsylvania

Time period: 2012-01-01--2013-12-31, 2014-01-01--2014-12-31, 2016-01-01--2016-12-31

Coverage expansion under the Affordable Care Act (ACA) has important implications for access, and the value of coverage is dependent on the ability to access care. Most information about access to care comes from household or physician surveys.

The current data collection was gathered as a part of the Primary Care Audit Study for 10 States in the United States, 2012-2013, 2014 and 2016 to assess variation in access to primary care using a methodology that was applied across different types of states (Arkansas, Georgia, Illinois, Iowa, Massachusetts, Montana, New Jersey, Oregon, Pennsylvania, and Texas) at baseline and over-time. The project was broken up into three phases: before the ACA (2012-2013), during the launch of ACA coverage provisions such as the Medicaid fee bump and ACA marketplaces (2014), and after the full ACA implementation (2016). Insurance types in the study included commercial coverage, Medicaid, uninsured, and, in 2014 and 2016, plans purchased on the ACA market place.

The audit-level file, featured in part one of the collection, includes all completed calls and provides information from multiple dimensions (appointment availability, wait times, simulated patients' demographics, cost information, etc.).

The office-level file, featured in part two of the collection, covers all eligible offices and their characteristics (e.g., size, insurance acceptability, cost information, etc.) collected from the screening phase.

Demographic variables include simulated caller number, race, gender, and age.

To start the interview, questions were asked regarding knowledge and support of radioactive waste disposal, as well as questions regarding the options of and preferences for nuclear energy. Respondents gave their views on the risks of radioactive waste disposal, the possibility of recycling noncontaminated materials from the nuclear industry, and the political and health-related consequences of handling dangerous waste. Next, questions were asked regarding transport services within the European Union (EU). Respondents gave their views on the rights of passengers, whether they were satisfied with the current transport services in EU countries, and their satisfaction with international travel within the EU. The third portion of the interview collected information on respondents' views on the welfare of farm animals. Questions were asked pertaining to the purchase and consumption of food derived from farm animals, respondents' views on the rights of farm animals, as well as their views and preferences regarding the protection of farm animals. Respondents gave their views on the purchase of eggs, meat, and milk from animal welfare-friendly production systems, their willingness to accept additional price premiums to ensure such production systems are used, and their perception of animal welfare in the EU versus other parts of the world. The last topic of the survey was means of payment. A series of questions addressed financial services in the EU, expectations of financial institutions, preferred payment options, and banking security. Background information includes respondent's age, gender, nationality, origin of birth (personal and parental), marital status, left-to-right political self-placement, occupation, age when they stopped full-time education, household composition, region of residence, and telephone equipment.

The Household Survey is one of the three major components of the 1987 National Medical Expenditure Survey (NMES). (The other two components are the Survey of American Indians and Alaska Natives [SAIAN] and the Institutional Population Component.) Like its predecessors, the 1987 NMES provides information on health expenditures by or on behalf of families and individuals, the financing of these expenditures, and each person's use of services. The Household Survey was fielded over four rounds of personal and telephone interviews at four-month intervals. Baseline data on household composition, employment, and insurance characteristics were updated each quarter, and information on all uses of and expenditures for health care services and sources of payment was obtained. The data on Public Use Tape 14.4 provide information on hospital stays, the major reason reported by household respondents for admission and related conditions, length of stay, medical procedures performed, cost of services, and means of payment. These data were collected in the four rounds of interviews and in the NMES Medical Provider Survey, a survey designed to reduce the potential bias in medical expenditure estimates derived solely from data provided by household respondents. The data file contains one record per hospital stay for each eligible person in the Household Survey who reported at least one stay during 1987.

The purpose of the National Medical Care Expenditure Survey (NMCES) was to assess the cost and extent of health insurance in the United States. Information on health insurance coverage was obtained in a household survey, then verified and supplemented with information from the Health Insurance/Employer Survey (HIES). Insurance companies, employers, unions, and other organizations identified in the household survey as sources of private insurance coverage were asked to verify reported coverage, to provide information on each subscriber's coverage and its cost, the parties responsible for payment of premiums, and the availability of alternative or optional plans. This release includes two distinct datasets. One contains information for each individual respondent in the NMCES component on private health insurance status as verified in the HIES, and includes data on premiums and sources of premium payment. The other contains information for each individual respondent 65 years or older with private insurance as verified in the HIES, as well as information on the services covered by their private insurance benefits.

The National Medical Expenditure Survey (NMES) series provides information on health expenditures by or on behalf of families and individuals, the financing of these expenditures, and each person's use of services. The Institutional Population Component (IPC) is a survey of nursing and personal care homes and facilities for the mentally retarded and residents admitted to those facilities. Information was collected on facilities and their residents at several points during 1987. Use and expenditure estimates for institutionalized persons can be combined with those from the Household component for composite estimates covering most of the civilian population. Information on facilities and residents was collected from facility administrators and caregivers, with additional information collected from next of kin or other knowledgeable respondents. These data were supplemented by Medicare claims information for covered sample persons. Public Use Tape 17 is the first release of expenditure and use data from the IPC. It provides demographic information such as race, age, sex, education, veteran status, medical history, income, family, date of admission, vital status, residence history, use of long-term care, insurance coverage, and home ownership. Additional information covers the respondent's institutional stays in 1987, dates and lengths of stays, and characteristics of the institution, including size, type, ownership, and certification status. Also provided are data on expenses and sources of payments for services rendered in nursing and personal care homes.

National Medical Expenditure Survey, 1987: Institutional Population Component, Personal History Questionnaire for Residents of Nursing and Personal Care Homes and End-of-Year Questionnaire for Residents of Nursing and Personal Care Homes and Facilities for Persons With Mental Retardation [Research File 19r] (ICPSR 6632)

Released/updated on: 2006-03-30

Geographic coverage: United States

Time period: 1987-01-01--1987-12-31

The National Medical Expenditure Survey (NMES) series provides information on health expenditures by or on behalf of families and individuals, the financing of these expenditures, and each person's use of services. The Institutional Population Component (IPC) is a survey of nursing and personal care homes and facilities for the mentally retarded and residents admitted to those facilities. Information was collected on facilities and their residents at several points during 1987. Use and expenditure estimates for institutionalized persons can be combined with those from the Household Component for composite estimates covering most of the civilian population. Information on facilities and residents was collected from facility administrators and caregivers, with additional information collected from next-of-kin or other knowledgeable respondents. These data were supplemented by Medicare claims information for covered sample persons. Research File 19R provides information collected from two IPC questionnaires, the Personal History Questionnaire (PHQ) and the End-of-Year Questionnaire (EYQ). The PHQ was administered once as part of the surveys of next-of-kin. These data are primarily concerned with the characteristics of the sample person just prior to admission. The EYQ was administered once in either the surveys of next-of-kin or the surveys of institutions and focuses on health status. Research File 19R also includes items from the Baseline Questionnaire and the Baseline Questionnaire Supplement. Data from these questionnaires were released on NMES Public Use Tapes 8, 17, and 22R (ICPSR 9677, 6158, and 6467). Part 1 of this collection, Summary Data, includes demographic characteristics such as age, race, sex, date of admission to sampled facility, and vital status. Part 2, 1987 Personal History Questionnaire (PHQ) Data, supplies information on condition prior to admission to facility, chronic disease history, whether respondent needed help with activities of daily living (ADLs) and/or instrumental activities of daily living (IADLs), usage of assistive technology, and behavioral history. Part 3, End-of-Year Questionnaire (EYQ) Data, includes characteristics of the sample person, limitations and help with ADLs and IADLs, health and behavioral history, and condition codes reported by either the respondent or the facility medical records.

National Medical Expenditure Survey, 1987: Survey of American Indians and Alaska Natives, Preliminary Ambulatory Medical Visit Data [Public Use Tape 23.5P] (ICPSR 6221)

Released/updated on: 2006-03-30

Geographic coverage: United States

Time period: 1987-01-01--1987-12-31

The National Medical Expenditure Survey (NMES) series provides information on health expenditures by or on behalf of families and individuals, the financing of these expenditures, and each person's use of services. The Survey of American Indians and Alaska Natives (SAIAN) was designed in collaboration with the Indian Health Service (IHS), and used the same data collection instruments, interview procedures, and time frame as the NMES Household Survey component. However, the SAIAN differed from the Household Survey in several respects. The SAIAN sample was interviewed only three times and was not given the supplements on long-term care, caregiving, and care-receiving. Also, SAIAN respondents were asked additional questions on topics such as use of IHS facilities and traditional medicine, and were given a modified self-administered questionnaire with separate versions for adults and children. Interviewers for the SAIAN were mainly American Indians or Alaska Natives, and about 20 percent of the interviews were not conducted entirely in English. Of these, approximately 40 percent were conducted entirely in the native language of the respondent. Public Use Tape 23.5 provides three data files containing information on the use of and expenditures for ambulatory medical services and sources of payment reported in the SAIAN Survey. An ambulatory visit is defined as a single contact with a medical provider for one or more services in either a hospital outpatient department or emergency room, a setting other than an inpatient hospital (such as a physician's office, a clinic, or a lab), a nursing home, or a person's home. The first file includes visits and telephone calls to physicians' offices (including HMOs and health departments) in settings other than a hospital or at home, and to providers of care (e.g., chiropractors and psychologists). The second file covers visits to hospital outpatient departments, while the third file provides information on visits to hospital emergency rooms, both regardless of provider type. A record on any of these data files represents a unique ambulatory visit. Variables include dates of visits, medical conditions associated with the visit, types of procedures performed, and the main reason for the visit. In addition, each file contains demographic information such as age, sex, and race.

National Medical Expenditure Survey, 1987: Health Insurance Plans Survey Data, Private Health Insurance of Household Survey Policyholders and Dependents [Public Use Tape 24] (ICPSR 6371)

Released/updated on: 2006-03-30

Geographic coverage: United States

Time period: 1987-01-01--1987-12-31

The National Medical Expenditure Survey (NMES) series provides information on health expenditures by or on behalf of families and individuals, the financing of these expenditures, and each person's use of services. Public Use Tape (PUT) 24 is the third release of data from the Health Insurance Plans Survey (HIPS). The HIPS is a follow-up to the NMES Household Survey and was designed to verify health insurance status reported by respondents to two components of the NMES, the Household Survey and the Survey of American Indians and Alaska Natives (SAIAN), as well as to provide supplementary information on private health insurance premiums and benefit provisions from employers, unions, and insurers through which coverage was provided. With PUT 24 the user can make person- and family-level estimates of the health insurance status of the entire civilian noninstitutionalized U.S. population at the end of 1987. Tape 24 contains three data files. File 1 contains data for persons in the NMES Household Survey. It includes the policyholders identified on Public Use Tape 15, NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: POLICYHOLDERS OF PRIVATE INSURANCE: PREMIUMS, PAYMENT SOURCES, AND TYPES AND SOURCE OF COVERAGE [PUBLIC USE TAPE 15] (ICPSR 9901), and their dependents, as well as persons without insurance and those with only public insurance. In addition, Tape 24 contains link files (Files 2 and 3) that enumerate each source of private insurance for each privately insured person in the HIPS. File 2 contains the linkages of all eligible policyholders and covered dependents with health insurance obtained from employers or unions, and File 3 contains the linkages of all eligible policyholders and covered dependents with health insurance obtained directly from insurance carriers or associations. These linkages identify the persons covered by each policyholder or all of the private insurance covering each person (whether obtained as a policyholder or dependent). The link files also identify the records in NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: HEALTH INSURANCE PLANS SURVEY DATA, PRIVATE INSURANCE BENEFIT DATABASE AND LINKAGES TO HOUSEHOLD SURVEY POLICYHOLDERS [PUBLIC USE TAPE 16] (ICPSR 6168) associated with each source of coverage, allowing the user direct access to the Private Insurance Benefit Database in PUT 16 in order to characterize the provisions of the insurance covering each person (sometimes through multiple sources). The three data files on Tape 24 can also be linked to all tapes from the Household Survey with the person identifier PIDX.

Time period: 1987-01-01--1987-12-31

The National Medical Expenditure Survey (NMES) series provides information on health expenditures by or on behalf of families and individuals, the financing of these expenditures, and each person's use of services. The Household Survey was fielded over four rounds of personal and telephone interviews at four-month intervals. Baseline data on household composition, employment, and insurance characteristics were updated each quarter, and information on all uses of and expenditures for health care services and sources of payment was obtained. Public Use Tape 29 provides information on disability days and household-reported medical conditions for 1987. There are five data files in this collection. Part 1, Medical Conditions Data, contains one record for each medical condition reported by a respondent. Variables include information on whether the respondent saw or talked to a medical provider about the condition, beginning and ending dates of the condition, whether the condition was due to an accident, the body area affected by the condition, and whether the respondent or a doctor discovered the condition. In Part 2, Disability Days Data, a record represents a unique disability defined by the combination of disability type and disability period. Variables describe up to four different types of disabilities due to illness or injury that were collected over the four rounds of the interviews. The types of disabilities are work-loss days, school-loss days, bed days, and restricted-activity days. In addition, beginning and ending dates of the disability period, number of disability days, and medical conditions associated with the disability period are also included. Part 3, Disability Days to Medical Conditions Link File, contains the variables necessary to link each disability days record in Part 2 with one or more of the condition records in Part 1. Variables include the type of event this record links to, condition number, condition ID, event number, event ID, person ID, and provider number. Part 4, Medical Conditions to Medical Utilization and Expenditures Link File, contains the variables necessary to link each condition record in Part 1 with one or more of the records contained in NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: PRESCRIBED MEDICINE DATA [PUBLIC USE TAPE 14.1] (ICPSR 9746), NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: HOUSEHOLD SURVEY DATA ON HOME HEALTH CARE AND MEDICAL EQUIPMENT PURCHASES AND RENTALS [PUBLIC USE TAPE 14.2] (ICPSR 9944), NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: HOUSEHOLD SURVEY, DENTAL VISIT DATA [PUBLIC USE TAPE 14.3] (ICPSR 9814), NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: HOUSEHOLD SURVEY, HOSPITAL STAYS DATA [PUBLIC USE TAPE 14.4] (ICPSR 9840), or NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: AMBULATORY MEDICAL VISIT DATA [PUBLIC USE TAPE 14.5] (ICPSR 9881).

Released/updated on: 2006-01-18

Geographic coverage: United States

Time period: 1987-01-01--1987-12-31

The National Medical Expenditure Survey (NMES) series provides information on health expenditures by or on behalf of families and individuals, the financing of these expenditures, and each person's use of services. Research File 40R includes data from several components of the NMES. These data were previously scheduled for release as NMES Research Files 27R, 33R, 38R, and 39R and have now been consolidated into a single collection, File 40R. Eight data files are contained in this collection. Parts 1-3 provide residence history and hospital inpatient stay data from the Institutional Population Component (IPC) (previously scheduled for release as NMES Research File 27R). Parts 4-5 cover all health insurance plans offered by potential employment-related sources (i.e., held plans and optional plans) from the Health Insurance Plans Survey (HIPS) (previously scheduled for release as NMES Research File 33R). Part 4 also includes update information on health insurance premium amounts for all policyholders of insurance from employment-related sources (previously scheduled for release as NMES Public Use Tape 15U, these data replace the premium variables originally released on NMES Public Use Tape 15, NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: POLICYHOLDERS OF PRIVATE INSURANCE: PREMIUMS, PAYMENT SOURCES, AND TYPES AND SOURCE OF COVERAGE [PUBLIC USE TAPE 15] [ICPSR 9901]). Parts 6-7 consist of summarized benefits data and actuarial values from the HIPS for linked policyholders and dependents (previously scheduled for release as NMES Research File 38R). Part 8 contains death certificate data for persons in the NMES Household Survey (HS), the IPC, and the NMES Survey of American Indians and Alaska Natives Component (SAIAN) (previously scheduled for release as NMES Research File 39R).

National Hospital Ambulatory Medical Care Survey, 1993 (ICPSR 6915)

Released/updated on: 2006-01-18

Geographic coverage: United States

Time period: 1992-12-28--1993-12-26

The National Hospital Ambulatory Medical Care Survey (NHAMCS) was inaugurated in 1992 to fill a gap in data about ambulatory medical care in the United States. Although the National Ambulatory Medical Care Survey (NAMCS) collects annual data on patient visits to physician offices, it excludes the hospital emergency room and outpatient department visits that make up a large part of the total ambulatory care received each year. The 1993 NHAMCS provides data from samples of patient records selected from emergency departments (EDs) and outpatient departments (OPDs) of a national sample of hospitals. The resulting national estimates describe the use of hospital ambulatory medical care services in the United States. For the 1993 survey, data were collected from 228 OPDs and 395 EDs. Among the variables included are age, race, and sex of the patient, reason for the visit, physician's diagnoses, cause of injury (ED only), surgical procedures (OPD only), medication therapy, and expected source of payment.

National Medical Care Utilization and Expenditure Survey, 1980 (ICPSR 8239)

Released/updated on: 2006-01-12

Geographic coverage: United States

Time period: 1980-01-01--1980-12-31

The National Medical Care Utilization and Expenditure Survey (NMCUES), 1980 was designed to produce a database of detailed information on the country's health status, patterns of health care utilization, charges for services received, and methods of payment. NMCUES consists of three components: the National Household Survey (HHS), the State Medicaid Household Survey (SMHS), and the Administrative Records Survey (ARS). The seven NMCUES public use files making up this data collection contain respondent data from the National Household Survey (HHS) only and include information on utilization, expenditures, conditions, disabilities, and demographic characteristics. The first six files in the collection provide information on medical visits, dental visits, hospital stays, prescribed medicines, and health conditions for all persons residing in the sample households at each of five interview sessions. The seventh (Family) file contains data from the first six files on key family reporting units or RUs (defined as an individual or group of persons related to each other by blood, marriage, adoption, or foster parent/child relationship, whose usual residence was the assigned sample housing unit) for which there were longitudinal data on (1) eligible residents at the time of the round one interview, their nonresident unmarried college students, and babies born into the families or members who returned from the military, institutions, or abroad during the year, and (2) new RUs formed by such key members during the year.
