National Neighborhood Data Archive (NaNDA): Broadband Availability by Census Tract and ZIP Code Tabulation Area (ZCTA) United States, 2025 (ICPSR 302937)
This dataset contains measures of broadband internet availability and performance per United States census tract and ZIP Code Tabulation Area (ZCTA) in 2025. The data is derived from internet service providers' reports to the Federal Communications Commission's Broadband Data Collection (BDC) program. Key variables include the number of internet service providers offering service, the proportion of housing units and land area with access to broadband, download and upload speed categories, low-latency service availability, and technology types for broadband connections.
Broadband availability measures include the proportion of housing units and land area served by any provider, as well as the number of unique providers offering service. Speed measures are categorized into multiple tiers for both download speeds (ranging from less than 10 Mbps to 2000+ Mbps) and upload speeds (ranging from 1 Mbps or less to 100+ Mbps). The dataset also includes combined download/upload speed categories, distinguishing between unserved areas (less than 25/3 Mbps), underserved areas (at least 25/3 Mbps but less than 100/20 Mbps), and served areas (at least 100/20 Mbps). Technology type measures identify the proportion of housing units and land area served by different broadband technologies, including fiber to premises, coaxial cable, copper wire, fixed wireless, and satellite.

Eurobarometer 74.3: The European Parliament, Energy Supply, Data Protection and Electronic Identity, Chemical Labeling and Rare Diseases, November-December 2010 (ICPSR 34264)
The Eurobarometer series is a unique cross-national and cross-temporal survey program conducted on behalf of the European Commission. These surveys regularly monitor public opinion in the European Union (EU) member countries and consist of standard modules and special topic modules. The standard modules address attitudes towards European unification, institutions and policies, measurements for general socio-political orientations, as well as respondent and household demographics. The special topic modules address such topics as agriculture, education, natural environment and resources, public health, public safety and crime, and science and technology.
This round of Eurobarometer surveys diverged from the Standard Eurobarometer measures and queried respondents on the following major areas of focus: (1) the European Parliament (EP), (2) energy supply, (3) data protection and electronic identity, (4) chemical labeling, and (5) rare diseases. For the first major area of focus, the European Parliament, respondents were asked about their knowledge and opinion of the EP, whether the EP should play a more important or less important role, which policies should be given priority by the EP, and which values should be defended by the EP. For the second major area of focus, energy supply, respondents were queried about what goals should be prioritized in energy policies, what energy policies should be adopted, and whether or not there should be a communal European Union (EU) energy policy. Additionally, respondents were asked whether they believed it was in their country's energy security interest to assist other EU member states facing energy supply problems, as well as whether they believed it was desirable that their country provide assistance to other EU member states in the name of European solidarity. For the third major area of focus, questions address activities one performs on the Internet, opinions about types of information and data considered to be personal, types of information disclosed on social networking and online shopping sites and the risks, and measures taken to protect one's identity. Opinions were also collected on how personal information and data are acquired, treated, stored and protected by public and private organizations. For the fourth major area of focus, chemical labeling, respondents were asked about their use and perception of chemical products in various circumstances, how they determine whether or not a chemical product is hazardous, what the proper handling of chemical products is, where respondents find information about the potential dangers of chemical products, who to trust for information about chemical product safety, and whether or not they could correctly identify chemical product warning labels. For the fifth major area of focus, rare diseases, respondents were interviewed about what they believe rare diseases are, whether or not they knew or heard of someone with a rare disease, what society should do about rare diseases, what specific policy responses to rare diseases should be implemented by national health services and the EU as a whole, as well as whether or not they had heard of certain rare diseases.
Demographic and other background information collected includes age, gender, nationality, marital status and parental relations, left-right political self-placement, occupation, age when stopped full-time education, household composition, ownership of a fixed or a mobile telephone, difficulties in paying bills, level in society, and Internet use. In addition, country-specific data includes type and size of locality, region of residence, and language of interview (select countries).

Information and Communication Technology (ICT) for Crown Prosecutors' Offices (ICPSR 22240)
Information and communication technology (ICT) are playing an important role in the criminal justice chain, but very little is known about public prosecutor's offices, while there is a strong need to exchange information among practitioners, decision makers, and scholars in order to share experiences, knowledge, and facilitate the adoption of common ICT solutions and practices in a cost-effective way.
This Research Project stresses the need to pursue judicial cooperation in the area of criminal law, and it contributes to fostering mutual knowledge of European legal and judicial systems as well as best practices and technological solutions. The Project is not limited to legal literature, but it has an inter-disciplinary approach, and it focuses on practical experiences and policies implemented. The project will lead to a conference to disseminate the information collected, to pass on knowledge of immediate use in carrying on professional activities, as well as to increase the number of practitioners, academics, and policy makers who will take advantage of and profit from the research. The research entails six in-depth case studies. Four of them will be carried on by the organizations' partners in this research: England and Wales, Finland, Italy, the Netherlands, two others are in the process to be identified.
After a description of the governance system of public prosecution in the countries considered in this study, since ICT application are not developed in a vacuum, the research will describe, study, and compare through an in-depth analysis: (1) the use of ICT in case investigations, (2) the use of ICT for case management, (3) the ICT interoperability between public prosecutor's offices, courts, police and prisons, and (4) the use of ICT for sharing prosecutorial information between countries.
The research will allow to: (a) detect the valuable and successful implementations of ICT in criminal investigations (e.g. decision support systems, access to data bases, multimedia applications), (b) disseminate technical information about these applications, (c) explore the feasibility for cross-border exchange of data such as criminal history records and illegal immigration records, (d) develop a network of scholars and practitioners about ICT for public prosecutor's offices.
This report structure, should serve as a guide to the researchers working on the various countries. It is divided into three main sections. Section 1 will deal with the institutional setting of public prosecutor. Section 2 will deal with ICT history, governance and infrastructures. Section 3 will deal with technologies for investigation and prosecution of crimes.
