The primary goal of the National Politics Study (NPS) was to gather comparative data about individuals' political attitudes, beliefs, aspirations, and behaviors at the beginning of the 21st century. Exploring the nature of political involvement and participation among individuals from different racial and ethnic groups, the survey included questions about voting preferences, party affiliation, organizational membership, immigration, racial consciousness, acculturation, and views of government policies.

The National Survey of American Life (NSAL) is a study designed to explore racial and ethnic differences in mental disorders, psychological distress, and informal and formal service use from within the context of a variety of presumed risk and protective factors in the African-American and Afro-Caribbean populations of the United States as compared with White respondents living in the same communities. The NSAL is part of the Collaborative Psychiatric Epidemiology Surveys (CPES) data collection.

This study was designed to provide information on attitudes and opinions regarding a number of issues of importance to Black Americans. Topics included the performance of President Bill Clinton, the economic condition of Black Americans, and what respondents thought ought to be done to improve the condition of Black people. Questions regarding Black women and their role in the Black community were also asked. In addition, the role and extent of religion in Black politics was investigated. Respondents also provided information about their political self-identification and their community and political involvement, as well as their feelings toward various political leaders, political groups, and national policies. Demographic information on respondents includes sex, age, education, marital status, income, and occupation and industry.

This data collection documents all cases of military intervention across international boundaries by regular armed forces of independent states in the regions of Europe, the Americas (and Caribbean), Asia and the Pacific, Sub-Saharan Africa, and the Middle East/North Africa. Military interventions are defined operationally in this collection as the movement of regular troops or forces (airborne, seaborne, shelling, etc.) of one country into the territory or territorial waters of another country, or forceful military action by troops already stationed by one country inside another, in the context of some political issue or dispute. The study seeks to identify politically important actions which interpose a state directly into the conflict patterns occurring in another state, and which conceivably involve a breach of the sovereignty of the target state (albeit by invitation in some cases). The collection identifies intervener and target countries and specifies the starting and ending dates of the intervention. A series of potential interests in or motives for intervention are presented, including effects on the target's domestic disputes, foreign or domestic policies, and efforts to protect social factions in the target, to attack rebels in sanctuaries across borders ("hot pursuit"), to protect or enhance economic/resource interests, to protect military or diplomatic facilities, to save lives, or to affect regional power balances and strategic relations. Information is provided on the direction of the intervention, i.e., to support or oppose the target government, to support or oppose opposition groups in the target, or to support or oppose third-party governments or opposition groups. Other variables show the degree of prior intervention, the alliance or treaty relationship between intervener and target, prior colonial status, prior intervention, and measures of intervener and target power size. A series of intensity measures, such as battle-related casualties, is also included. For each type of incursion, by land, sea, or air, an ordinal scale of involvement is presented, ranging from minor engagement such as evacuation, to patrols, acts of intimidation, and actual firing, shelling, or bombing. Finally, contiguity information is provided to indicate both whether intervener and target are geographically contiguous, and whether the intervention was launched from contiguous territory.

The NAEP data Explorer (NDE) creates customizable tables and graphics to display NAEP results. See the results of specific assessments across multiple years and broken down across a variety of student groups. For some assessments, results are available by state or by participating urban district. Results can be filtered by content areas within subjects. For in-depth exploration, the NDE provides statistical results such as significance testing, gap analysis, and regression analysis. You can export tables and charts to Word documents, Excel workbooks, and PDFs.

The National Health and Nutrition Examination Survey (NHANES) is a program of studies designed to assess the health and nutritional status of adults and children in the United States. The survey is unique in that it combines interviews and physical examinations. NHANES is a major program of the National Center for Health Statistics (NCHS). The NHANES program began in the early 1960s and has been conducted as a series of surveys focusing on different population groups or health topics. In 1999, the survey became a continuous program that has a changing focus on a variety of health and nutrition measurements to meet emerging needs.
