Details

The three variables with the prefix of un nominally come from the United Nations Statistical Division for 1949/1950, but are actually retrieved from Andic and Peacock (1961). Andic and Peacock (1961) note you should be skeptical of Soviet-style calculations of national income and thus don't include it in the data they make available.

Anything else is explicitly benchmarked to 1950 as a referent year. The GDP and population estimates come by way of Anders et al. (2020). You can manually create your own GDP per capita variable here because the GDP is demarcated in dollars and the population size is in units of 1. Take one and divide it over the other.

The democracy variables are all unique in their own way. The "Quick UDS" estimates are generated to be latent and, globally, have a mean that approximates 0 and a standard deviation that approximates 1. In the regression context, that would mean a coefficient would communicate something like a magnitude change across a standard deviation on the scale. The "polyarchy" estimate has a theoretical minimum of 0 and a theoretical maximum of 1. In the regression context, that would mean a coefficient communicates a min/max effect. The Polity project estimate comes from a usual scale of -10 to 10 and a regression coefficient communicates something much less exotic. It's a unit change on this scale.

In all cases, higher values of democracy = more "democraticness", for lack of a better term.
