Fig. 2: Fluctuations in relative growth rate (RGR, change in Summed Probability Distribution, SPD) in all populated continents.

From: Multicentennial cycles in continental demography synchronous with solar activity and climate stability

Fig. 2

a–d Phase relationships between continental population cycles. Phases of either positive or negative RGR of the first continent are shaded. Percentage shows relative phase overlaps (see Methods). d–j Phase relationships between continental RGR with negative total solar irradiance (TSI, with shading for positive and negative phases, resp.). All time-series in (a–j) were normalized (division by standard deviation σ), smoothed and detrended.
