• 'Brain Drain' Debate in the United Kingdom, c.1950-1970
  Qualitative project. Sought to provide an analysis of the 'brain drain' debate of the 1950s and 1960s as a social phenomenon. The term 'brain drain' was adopted in the 1960s in the context of concerns the United Kingdom was losing skilled scientific and engineering personnel to other countries. Although the term is used in a variety of academic, policy and popular discussions about the international mobility of scientists, this project sought to rectify the absence of scholarly literature analyzing the original 'brain drain' debate. Comprised of 19 oral history interviews with scientists and engineers who emigrated to the United States or Canada in the 1950s or 1960s as well as British policymakers involved in any way in the 'brain drain' debate at this time. Also included is the transcript of a 'witness seminar' that brought officials and former emigres together to discuss their recollections. To obtain a free account please register with the UKDA.

• Afghan Women's Resistance and Struggle in Afghanistan and Diasporic Communities, 2004-2005
  Aimed to develop a better understanding of Afghan women's resistance to war and violent conflicts; their engagement with multiple worlds as refugees or living in exile, their struggle for survival and/or their acquisition of new knowledge and power. Investigated the vast diversity (class, age, ethnicity, religion) of women's experiences in the process of historical changes (in times of war and conflict, in exile and in times of peace making) and the different ways they emerge as autonomous agents and construct their identities, in culturally specific circumstances. Assessed the gendered nature of social exclusion, and the importance of women's inclusion in the processes of reconstruction and peace making. Semi-structured interviews were used to study Afghan women (and some men) in Afghanistan, Iran, Pakistan, UK and USA. Respondents were chosen to represent a sample of diverse groups (students, teachers, non-Governmental Organisation workers, United Nations workers, journalists, women and men in refugee camps) according to their religiosity, ethnicity, age, marital status, fertility rate, class, citizenship status, employment status and political, social and cultural activities. Detailed demographic information about each respondent is recorded in the data listing. To obtain a free account please register with the UKDA.

• Attitudes in Russia to Social and Political Aspects of Human Trafficking, 2007
  Collected representative data across Russian regions on attitudes to human trafficking. Since the collapse of the Soviet state, thousands of Russian citizens have been trafficked out of the country as exploited labour, sex slaves, domestic labour, and beggars. Explored beliefs concerning the origins, nature and extent of human trafficking, and attitudes on what the Russian government should do to address the problem. Captured attitudes on how the state should aid the trafficked and the perceived efficacy of different institutions in dealing with trafficking. It also sought responses on how families should help or not help the trafficked; beliefs on the place of a woman in society, and attitudes towards prostitution.

• Comparative Immigrant Entrepreneurship Project (CIEP)
  Survey of over 1,200 Colombian, Dominican, and Salvadoran family heads is the first to explicitly measure the extent of economic, political, and socio-cultural transnationalism among immigrants and to develop predictive models of these activities.

• Comparative Immigrant Organization Project (CIOP)
  This survey of 89 Colombian, Dominican, and Mexican organization leaders and additional interviews with community activists and government officials is part of a larger study of the organizations constructed by Latin American immigrants in the United States and their impact on the political incorporation of these immigrants to American society. This specific dataset was designed to give us greater understanding of the forces creating and sustaining these organizations and to test several preliminary hypotheses about the effects of contexts of exit and modes of incorporation in receiving countries on the character of immigrant transnationalism. Accordingly, there are detailed measures of the extent of economic, political, and socio-cultural transnationalism and characteristics of both the organizations and their members.

• County-to-County Migration Flows
  The American Community Survey (ACS) and the Puerto Rico Community Survey (PRCS) ask respondents age 1 year and over whether they lived in the same residence 1 year ago. For people who lived in a different residence, the location of their previous residence is collected. ACS uses a series of monthly samples to produce estimates. Estimates for geographies of population 65,000 or greater are published annually using these monthly samples. Three years of monthly samples are needed to publish estimates for geographies of 20,000 or greater and 5 years for smaller geographies. The 5-year dataset is used for the county-to-county migration flows since many counties have a population less than 20,000. The first 5-year ACS dataset covers the years 2005-2009. In addition to the county-to-county flow files, there are similar files that substitute minor civil divisions (mcd), in place of counties, for states where they serve as general-purpose local governments. These states are Connecticut, Maine, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and Wisconsin.

• Cuban and Mexican Immigrants in the U.S.

Listings documenting the occurrence of current population survey supplements by topic and month are available. Questionnaires and codebooks are available at the Census Bureau site. For comparisons of CPS, Survey of Income and Program Participation, and the Panel Study of Income Dynamics, see the comparison chart. See the Current Population Reports series for summary reports and methodological papers. While geography is at the state, county, or metropolitan statistical area level, one should use with caution for detailed geography due to the sample size.

• Displaced New Orleans Residents Pilot Study (DNORPS)
  Designed to examine the current location, well-being, and plans of people who lived in the city of New Orleans when Hurricane Katrina struck on August 29, 2005. Based on a representative sample of pre-Katrina dwellings in New Orleans. Fieldwork focused on tracking respondents wherever they currently resided, including back to New Orleans. The pilot study was fielded in the fall of 2006. The goal was to assess the feasibility of the study design and thereby to lay the groundwork for launching a major longitudinal study of displaced New Orleans residents. The follow up is The Displaced New Orleans Residents Survey (DNORS).

• Dynamics of Household Land Use and Economic Welfare on the Amazon Frontier, 1996-2005, Rondonia, Brazil
  Examines household land use and economic welfare in the Amazon basin, through the collection of a third round of panel data with improved spatial referencing and a new system for tracking households and individuals. The study area is typical of the arc of deforestation across the southern Brazilian Amazon. Data from this study were used to model the relationship between deforestation and household well-being, thereby gaining insight on welfare outcomes that also have implications for conservation policies. Face-to-face interviews were conducted with the residents of the Ouro Preto do Oeste region of the Brazilian state of Rondonia. Demographic questions focused on: education, age, household size, migration and place of birth of the residents. Other questions focused on the ownership of the lots, years of residency on the lots, household income sources, household wealth and assets, as well as household cost of living.

• Egypt Integrated Household Survey, 1997-1999
  The 1997 questionnaire was administered to 2,500 households from 20 governorates using a two-stage, stratified selection process from March through May, 1997. Topics include household information, housing characteristics, access to facilities, migration, subsidized food expenses, all food expenses, non-food expenses, health, anthropometrics, maternity history, childcare, wage employment, farming, livestock ownership, non-farm enterprises, credit and savings, remittances and transfers, and other income.

The EIHS 1999 household questionnaire consists of the following sections or topics: household Information, housing characteristics, Income Sources, food expenses, non-food expenses, farming, livestock ownership, non-farm enterprises, non-farming assets, and other income sources, and subsidized food expenses.

• Ethiopian Rural Household Survey Dataset, 1989-2009 (ERHS)
  Longitudinal household data set covering households in a number of villages in rural Ethiopia. Data collection started in 1989, when a team visited 6 farming villages in Central and Southern Ethiopia. In 1989, IFPRI conducted a survey in 7 Peasant Associations located in the regions Amhara, Oromiya and the Southern Ethiopian People's Association (SNNPR). Civil conflict prevented survey work from being undertaken in Tigray. Under extremely difficult field conditions, household data were collected in order to study the response of households to food crises. The study collected consumption, asset and income data on about 450 households. In 1994, the survey was expanded to cover 15 villages across the country. An additional round was conducted in late 1994, with further rounds in 1995, 1997, 1999, 2004, and 2009. In addition, 9 new villages were selected giving a sample of 1477 households. The 9 additional communities were selected to account for the diversity in the farming systems in the country, including the grain-plough areas of the Northern and Central highlands, the enset-growing areas and the sorghum-hoe areas. Topics addressed in the survey include household characteristics, agriculture and livestock information, food consumption, health, women's activities, as well as community level data on electricity and water, sewage and toilet facilities, health services, education, NGO activity, migration, wages, and production and marketing.

• Immigration and Intergenerational Mobility in Metropolitan Los Angeles (IIMMLA), 2004
  Focused on young adult children of immigrants (1.5- and second-generation) in greater Los Angeles. Investigated mobility among young adult (ages 20-39) children of immigrants in metropolitan Los Angeles and, in the case of the Mexican-origin population there, among young adult members of the 3rd- or later generations. The 5-county Los Angeles metropolitan area (Los Angeles, Orange, Ventura, Riverside and San Bernardino counties) contains the largest concentrations of Mexicans, Salvadorans, Guatemalans, Filipinos, Chinese, Vietnamese, Koreans, and other nationalities in the United States. Compared 6 foreign-born (1.5-generation) and foreign-parentage (second-generation) groups (Mexicans, Vietnamese, Filipinos, Koreans, Chinese, and Central Americans from Guatemala and El Salvador) with 3 native-born and native-parentage comparison groups (3rd- or later-generation Mexican Americans, and non-Hispanic Whites and Blacks). The targeted groups represent both the diversity of modes of incorporation in the United States and the range of occupational backgrounds and immigration status among contemporary immigrants (from professionals and entrepreneurs to laborers, refugees, and unauthorized migrants). Provides basic demographic information as well as extensive data about socio-cultural orientation and mobility (e.g., language use, ethnic identity, religion, remittances, intermarriage, experiences of discrimination), economic mobility (e.g., parents' background, respondents' education, first and current job, wealth and income, encounters with the law), geographic mobility (childhood and present neighborhood of residence), and civic engagement and politics (political attitudes, voting behavior, as well as naturalization and transnational ties).

• International Migration Flows to and from Selected Countries: The 2005 Revision
  Time series data on the flows of international migrants as recorded by Australia, Belgium, Canada, Denmark, Finland, France, Germany, Italy, the Netherlands, New Zealand, Norway, Spain, Sweden, the United Kingdom and the United States. Each file has a complete set of the data available for a given country in Excel format. The period for which data are presented varies from country to country. In a majority of cases, an effort has been made to cover the period 1960-2004. However, some countries lack data for the early 1960s and the most recent data available for some countries is 2003. For countries that were not major receiving countries in the 1960s (Denmark, Finland, Italy, Norway and Spain), their time series start in 1980. Countries gathering and publishing statistics on the flows of international migrants do not use the same criteria to identify migrants nor do they classify them in similar ways in terms of origin. Each file in the contains several worksheets. The first worksheet contains data on immigration, the second worksheet contains data on emigration when available, and the third worksheet shows data on net migration, the difference between immigration and emigration when both series are available. Users should be aware of the problems of comparability underlying existing statistics.

• Market for Migrant Domestic and Sex Workers, 2002-2006
  Explored attitudes towards, and experience of, the markets for migrant domestic and sex workers in the Czech Republic, Hong Hong, Spain, Thailand, and the UK through a combination of interview and survey research. Interviews were structured around a standard set of topics, and examined respondents' attitudes towards gender, race/ethnicity, age, and domestic work/commercial sex. It aimed to examine continuities and discontinuities between domestic work and sex work, paying particular attention to the role of the social/cultural imagination in constructing a market for migrant workers and questions about how this demand relates to broader socially tolerated attitudes towards race, gender, age and sexuality, and to make a contribution to current theorizing on gender, nationality, global interdependence, age, racial/ethnic identities and the complex intersections among these systems.

• Politics and the Migrant Poor in Mexico City, 1970-1972
  Comparative study of male migrants and their city-born neighbors living in 6 relatively small, predominately low-income communities on the periphery of Mexico City. Dealt with a relatively small group of people in a limited number of localities at a particular point in time. The research addressed several broad theoretical and empirical problems such as the most important incentives and disincentives for political involvement, the effect a large group of people entering the political arena has on the functioning of the political system, how the individual citizen -- and especially the disadvantaged citizen -- can manipulate the political system to satisfy their needs, the process by which individuals form images of politics and the political system, the process by which individuals assume a role of participation or non-participation in political activity, what occurs at the "grass roots" of a nation's political system, and how political activity at that level affects system outputs. Attempted to place the low-income migrant in a social and political context, and focused on the nature and frequency of interactions between the research communities and external actors, especially political and government officials. Demographic variables include age, race, socio-economic status, marital status, dwelling unit type, and religious preference.

• Scottish Demography: Scottish Migration to, and Return from, South East England, 2005-2006
  Examined Scots living in England. Scots are one of the largest non-English born immigrant groups in the UK. While the attraction of Scotland to the English-born population is documented, less attention is given to why Scots continue to migrate to England (albeit in lower numbers) and how the employment and progression opportunities, especially in the South Eastern England labor market compare with opportunities in Scotland. This is important in the context of concern about Scotland's demographic regime and the significant reduction in numbers projected over the next 3 decades.
