Table 4. Summary of gridded data (presented dataset) countries aggregated to administrative region level 1 and 2 for year 2005 and compared with GPWv4.

	n	r2	RMSE	GPWv4 average population	Gridded average population	GPWv4 country population	SSP country population
SSP country population is the population from the SSP scenarios that the product is based on. The SSP population scenarios do not deviate until after year 2005. n indicates number of regions within each administrative level. r2 is the coefficient of determination and RMSE is the root mean square error between GPWv4 and gridded population, aggregated to administrative level one or two.
