Uganda Survey of War Affected Youth

A long run tracking survey of 1300 young men and women who grew up in the midst of war in northern Uganda.

Historic Commodity Prices (1865-1950)

Blattman, Hwang, and Williamson (2007) compile a country-specific commodity price index and commodity weights for 35 countries, 1865-1950. See Blattman's website for more detail.

Commodity Price Statistics

See Section 3 of Ghoshray (2011).

Also see Chris Blattman's website for the Raw Commodity data compiled by Sami Bazzi and Chris Blattman: the international price in every major commodity traded on international markets during 1957-2009.

Population of cities around the world over time

According to Cuberes (2011), there are three time-series (every decade) datasets on the population of cities in many countries.

  1. Vernon Henderson: data on metropolitan areas (henceforth, MAs) in different countries during the 1960–2000 period.
  2. Thomas Brinkhoff: information on the populations of various administratively defined cities (henceforth, cities) in 79 countries during the 1970–2000 period. 
  3. Jan Lahmeyer, the most comprehensive dataset, includes the size of the largest cities for all countries up to the year 2000 and going as far back as 1790 in some cases. 
Minhas and Radford (2016) use The World Alamanac, which "lists the major cities in a country by population... Typically, the Almanacs list at least three major cities, including the capital, for each country and year from 1989 to 2008. Because the Almanacs are not perfectly consistent from year to year, we opted to code cities with a five-year rolling window. That is, cities listed in the 1995 Almanac are also included in our data set for years 1993 to 1997. In doing so, we hope to minimize the effect of coding inconsistencies on the part of The World Almanac."

Historical population estimates

1. Atlas of World Population History by McEvedy and Jones (1978)
  • Only available at the country level.
  • Data quality for Central America seems unreliable
  • The data for 1500 is used by Spolaore and Wacziarg (2013) as a measure of economic performance in 1500 (see their footnote 3 for justification)
2. Krumhardt, K. (2010). ‘Methodology for worldwide population estimates: 1000 BC to 1850’, ARVE Technical Report no. 3.
  • Used by Fenske (2013) as an alternative data source of historical population to McEvedy and Jones (1978)
  • Available at the subnational level across the world
  • Available at the subnational level across the world for some countries in the Americas

Mobile Coverage Explorer

Collins Bartholomew distributes mobile phone coverage maps on behalf of the GSMA (an association of major GSM mobile service providers around the world). It is not for free of charge.

Used by various papers that look at the impact of mobile phones, including Pierskalla and Hollenbach (2013)Gonzalez (2015) "Social Monitoring and Electoral Fraud: Evidence from a Spatial Regression Discontinuity Design in Afghanistan" and Manacorda and Tesei (2016) "Liberation Technology: Mobile Phones and Political Mobilization in Africa".
