Choose a cohort
Open one mutually exclusive population state, one independent demographic milestone, or a separately defined age-structure comparison. States partition the Register; the other groups can overlap.

Population states
Growing
Annual population change is above the 0.05% near-stationary threshold.
Near stationary
Annual change is within 0.05% of population, with a half-person source-precision floor.
Declining
Annual population change is below the threshold for fewer than five consecutive years.
Sustained decline
Total population change—including net migration—has remained below the threshold for at least five consecutive years.
Milestones
Below replacement reference
Total fertility rate is below the approximate 2.1 low-mortality reference; actual replacement fertility varies.
Working-age peak passed
The highest 15–64 population in the source series occurs before the display year.
Natural decrease
Deaths exceed births in the display-year series.
Migration offset
Natural change is negative while total population change remains non-negative.
Migration-led decline
Natural change is non-negative while total population change is negative.
Total population peak passed
The highest total population in the source series occurs before the display year.
