The GDP data includes 175 countries (or regions). It also provides electricity consumption data for 134 countries (or regions). As such, the research scope covers over 70% of the global land area, and over 90% of the GDP and electricity consumption. It is provided as millions of 2017 US dollars. "We employed nighttime light data to revise the real GDP growth rate. In particular, the real GDP growth rate was estimated using Eq: y∗i,t=ρyi,t+(1−ρ)y′i,t where y∗i,t is the ith country’s real GDP growth in period t; yi,t is the official GDP growth of the ith country in period t; y′i,t presents the ith country’s predicted GDP growth based on the night-time light data in period t; and (1−ρ) is the optimal weight of predicted growth based on the night-time light data." "Next, based on the gridded real GDP growth rate during 1993–2019, the gridded GDP data in 1992 or 2019 were estimated as basic values to obtain the gridded real GDP data in other years. Since the DN values in newly built-up areas were zero in 1992, these areas’ basic GDP values in 1992 were also zero, thereby leading to values of zero in subsequent years. Thus, the gridded GDP data in 2019 was selected as the basic value, which was calculated based on the top-down method. Finally, the gridded real GDP based on the real growth rate can be calculated."
