  1. The first column lists the number of countries with coverage within our core set of variables for each year of the Gallup World Poll, after some imputation done in accordance with the data appendix of Helliwell et al.8. The All data column lists the number of countries with all of our core variables. The Balanced column shows the number of countries in the largest balanced (complete, rectangular) panel covering all years after 2006. For our two-period model, we use the countries with at least one observation in the early period and at least one observation in the later period
