The GDL Area Database Website contains indicators at the national and sub-national level for low and middle income countries (LMICs) that were created by aggregating data from household survey datasets.
These datasets were obtained from the producing organizations for research by GDL-connected researchers. The aggregated indicators in the GDL Area Database can be seen as outcomes of this research. Making them available through our website is one of our ways of publishing research results. Another way is through scientific publications.
Demographic and Health Surveys (DHS)
DHS are large representative household surveys that provide data for a wide range of monitoring and impact evaluation indicators in the areas of population, health, and nutrition. Standard DHS Surveys have large sample sizes (usually between 5,000 and 30,000 households). Each survey consists of a household interview, in which basic information is collected on all household members, and separate women’s and men’s surveys. In the women’s survey, all usual resident women aged 15 to 49 are invited for an oral interview. The men’s surveys are generally smaller and show more variation across countries. In the interviews, information is obtained on socioeconomic, demographic, and (reproductive) health related issues. Since the 1980s over 300 DHS surveys have been held in all regions of the developing world. For most countries, several surveys have been held in different years, allowing comparisons over time. Producer of the DHS datasets is ICF International and major sponsor of the programme is the U.S. Agency for International Development (USAID). Further information is available at www.dhsprogram.com.

UNICEF Multiple Indicator Cluster Surveys (MICS)
UNICEF supports countries to collect data on the situation of children and women through the Multiple Indicator Cluster Survey (MICS) programme. The MICS was originally developed in response to the World Summit for Children to measure progress towards an internationally agreed set of mid-decade goals. Since the initiation of the programme, several rounds of surveys have been carried out and close to 300 MICS have been carried out in more than 100 countries, generating data on key indicators on the well-being of children and women, and helping shape policies for the improvement of their lives. MICS has been a major source of data on the Millennium Development Goals (MDG) indicators and will continue to be a major data source during the 2030 Sustainable Development Agenda to measure Sustainable Development Goals (SDGs) indicators. Further information is available at mics.unicef.org.
In the GDL Area database currently data from 144 MICS surveys for 79 countries are used:

Afrobarometer is an African-led, non-partisan research network that conducts public attitude surveys on democracy, governance, economic conditions, and related issues across more than 30 countries in Africa and are repeated on a regular cycle. Each of the barometers is implemented independently. In each country, a national research team administers a country-wide face-to-face survey using standardized survey instruments to compile the required micro-level data under a common research framework and research methodology. Core donors for Afrobarometer Rounds 5 and 6 include: The Mo Ibrahim Foundation, The Swedish International Development Cooperation Agency (SIDA), Department for International Development (DFID), UK and The United States Agency for International Development (USAID). Supplemental funding is provided by: The World Bank, Institute for Security Studies (South Africa), United States Institute of Peace, Transparency International and The Bill & Melinda Gates Foundation. Further information is available at www.afrobarometer.org.
In the GDL Area database currently for 4 countries data from Afrobarometer surveys is used. Because the Afrobarometer surveys are relatively small, generally data for several years are combined and an in between year is mentioned (e.g. 2013 is 2012 and 2014).
Americas Barometers (LAPOP Surveys)
The AmericasBarometer is an scientifically rigorous comparative survey that covers all of the mainland independent countries in North, Central, and South America, as well as a significant number of countries in the Caribbean. The AmereicasBarometer is part of the Latin American Public Opinion Project (LAPOP) of the Department of Political Science of Vanderbilt University. With the AmericasBarometer, LAPOP measures values, behaviors, and socio-economic conditions in the Americas using national probability samples of voting-age adults. Stratified sample designs, available on LAPOP’s website, permit complex analyses of individuals nested within sub-regions. Survey participants are voting-age adults interviewed face to face in their households, except in Canada and the United States where the interviews are Web-based. Major supporters of LAPOP are the United States Agency for International Development, the Inter-American Development Bank, and Vanderbilt University. Further information is available at www.vanderbilt.edu/lapop
In the GDL Area database currently for 9 countries data from Americas Barometer surveys is used. Because the Americas Barometer surveys are relatively small, generally data for several years are combined and an in between year is mentioned (e.g. 2012 is 2010 and 2014).

Other data sources
For China 2002, data from the Chinese Household Income Project is used. The purpose of this project was to measure and estimate the distribution of personal income and related economic factors in both rural and urban areas of the People's Republic of China. Data were collected through a series of questionnaire-based interviews conducted in rural and urban areas at the end of 2002.
For China 2011, 2013 and 2015 data from the Chinese Household Finance Survey is used. This survey was conducted by the Research Center for China Household Finance, a non-profit institute for academic inquiry, based at Southwestern University of Finance and Economics (SWUFE). The China Household Finance Survey (CHFS) contains detailed information about household finance and assets, including housing, business assets, financial assets, and other household assets, plus information about income and expenditures and social and commercial insurance.
For India 2012, data from the [Indian Human Development Survey] (https://www.ihds.umd.edu/) is used. The IHDS is a nationally representative, multi-topic panel survey of 41,554 households in 1503 villages and 971 urban neighborhoods across India. IHDS has been jointly organized by researchers from the University of Maryland and the National Council of Applied Economic Research (NCAER), New Delhi. Funding for the second round (used here) was provided by the National Institutes of Health, grants R01HD041455 and R01HD061048 and The Ford Foundation.
For Algeria besides MICS data also data from the Algerian (2002) PAPFAM survey is used.
For Malaysia besides IPUMSdata also data from the Malaysian (2011) Asian Barometer survey is used.
The national population figures used to compute the area population sizes are derived from the World Development Indicators of the World Bank.
The Global Data Lab and its connected researchers are grateful to the abovementioned organizations for their efforts to collect and process high-quality data and to make this data freely available to researchers worldwide. We are also greatly indebted to all survey respondents who were prepared to deliver the invaluable information about themselves and their living situation that made it possible to create the development indicators presented here.
