Global Entrepreneurship Monitor [GEM]: Adult Population Survey Data Set, 1998-2010 (ICPSR 20320)

Principal Investigator(s):


The Global Entrepreneurship Monitor (GEM) was designed to capture various aspects of firm creation and entrepreneurship across countries. The data have been collected over the course of 12 years (1998-2010) and include responses from individuals in over 90 countries. This dataset is a harmonized file capturing results from all of the surveys. The procedure has been to harmonize the basic items across all surveys in all years, followed by implementing a standardized transform to identify those active as nascent entrepreneurs in the start-up process, as owner-managers of new firms, or as owner-managers of established firms. Those identified as nascent entrepreneurs or new business owners are the basis for the Total Entrepreneurial Activity [TEA] or Total Early-Stage index. This harmonized, consolidated assessment not only facilitates comparisons across countries, but provides a basis for temporal comparisons for individual countries. Respondents were queried on the following main topics: general entrepreneurship, start-up activities, ownership and management of the firm, and business angels (angel investors). Respondents were initially screened by way of a series of general questions pertaining to starting a business, such as whether they were currently trying to start a new business, whether they knew anyone who had started a new business, whether they thought it was a good time to start a new business, as well as their perceptions of the income potential and the prestige associated with starting a new business. Demographic variables include respondent age, sex, and employment status.

Sample:   Representative samples based on RDD land line and cell phones in developed countries, supplemented with stratified geographic samples in rural areas of developing countries. For additional information on sampling, please refer to the Original P.I. Documentation section in the ICPSR Codebook.

Kind of Data:   quantitative

Weight:   The data are not weighted, however, this collection contains three weight variables that should be used in any analysis: WEIGHT, WEIGHT_L, and WEIGHT_A. National survey vendors implemented weights that would match the annual cohorts with the best available national data, later adjusted by matching the sample to the U.S. Census Bureau International Data Base (IDB) on national population distributions by age and gender. For more information on weights and sampling please refer to the Original P.I. Documentation section in the ICPSR Codebook.

Mode of Data Collection:   computer-assisted personal interview (CAPI), computer-assisted telephone interview (CATI), face-to-face interview, paper and pencil interview (PAPI), telephone interview

Extent of Processing:  ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Standardized missing values.
  • Created online analysis version with question text.
  • Checked for undocumented or out-of-range codes.
