Methodology

The indicators held in the database have been selected, and in some cases recomputed, by experts, so their values may differ from those published officially by national and international statistical agencies. This page records, for each indicator, where the figures come from and how they were obtained.

An empty cell means the source holds no data. It is never replaced by zero.

Depth of the series

Most series begin in 1900. Before that year the database holds 637 values for 15 territories; the earliest year is 1840. The deepest series is “Total birth cohort fertility” (1840); the other early series are shorter and scattered. On the Database page the period follows the indicator you choose, so these years show up straight away.
