What the data shows
Computed with the same code as the observations under the main chart and in the API (get_insights). Moving together in time does not prove a cause.
How the indicators changed
- Fertility (TFR): 3.22 in 1950 → 0.80 in 2023 (−75%). Low: 0.71 in 2018; +13% since then. Thresholds: below 2.1 since 1970, below 1.5 since 2005, below 1.0 since 2016. The trend broke around 1978 and 2006: −0.07 → 0 → −0.05 a year.
- Births: 0.05k in 1950 → 0.05k in 2023 (+8%). Peak: 0.09k in 1989; the latest value is 41% lower. The trend broke around 1980 and 1988: 0k → +0.01k → 0k a year.
- Population: 2.01k in 1950 → 11.1k in 2023 (×5.5). The trend broke around 1980: change sped up (+0.03k → +0.25k a year).
- Net migration: on average 0k a year in the 1950s, −0.01k a year in the 1960s, 0.03k a year in the 1970s, 0.17k a year in the 1980s, 0.12k a year in the 1990s, 0.14k a year in the 2000s, 0.12k a year in the 2010s, 0.21k a year in the 2020s.
- Life expectancy, men: 52.3 years in 1950 → 81.5 years in 2023 (+29 years). Thresholds: above 70 years since 1986, above 80 years since 2020.
What changed at the same time
- The fastest decline of "Fertility (TFR)" was in 1967–1977: 2.29 → 1.41. Over the same years: births 0.06k → 0.04k; population 2.39k → 2.72k; net migration −0.02k a year → 0.08k a year; life expectancy, men 60.7 years → 66.8 years.

Against other countries
- Order of events: fertility below 3: 1957; fertility below 2.1: 1970.
Forecasts vs actual
- Fertility (TFR): past UN projections. The outcome was below the projection in 1 of 1 revisions (2022–2022) and above in none; median gap −22%.
- Fertility (TFR): UN 2024 projection (medium): 2050 — 1.07 (+34% vs 2023), 2100 — 1.31 (+64% vs 2023); low variant for 2100: 0.81.
- Births: past UN projections. The outcome was below the projection in 1 of 1 revisions (2022–2022) and above in none; median gap −42%.
- Births: UN 2024 projection (medium): 2050 — 0.09k (+72% vs 2023), 2100 — 0.05k (−6% vs 2023); low variant for 2100: 0.01k.
- Population: past UN projections. The outcome was below the projection in 0 of 2 revisions (2019–2022) and above in 2; median gap +5.9%.
- Population: UN 2024 projection (medium): 2050 — 12.8k (+15% vs 2023), 2100 — 9.24k (−17% vs 2023); low variant for 2100: 6.25k.
- Why the UN missed the population. The 2022 projection for 2023: 11k; the UN's 2024 estimate: 11.1k (+0.9%). Parts of the gap (plus means more people than projected): the starting population −0.1k, births −0.1k, deaths 0 (fewer deaths than expected), migration +0.3k; the largest: migration.
- Net migration: UN 2024 projection (medium): 2030 — 0.11k a year, 2050 — 0.03k a year, 2100 — 0k a year.
- Life expectancy, men: UN 2024 projection (medium): 2030 — 82.3 years, 2050 — 84.5 years, 2100 — 89.7 years.
UN projections vs actual
Solid line: actual data, UN WPP 2024 estimates; births and fertility from national statistics from the last year they matched the UN estimate (the UN's figures for the latest years are partly its own projection). Dashed: medium variants of past UN revisions. The table shows what each revision expected for the latest year (or five-year period) with actual data.

Security
Deaths in organised violence
0 persons a year latest value, 2025
Deaths in state-based conflict, non-state conflict and one-sided violence against civilians, by where the events took place (UCDP GED, best estimate). 0 means no organised violence above UCDP thresholds (25 deaths a year in one conflict). Events in Gaza and the West Bank are counted for Palestine.
Deaths in organised violence per 100,000
0 per 100,000 people a year latest value, 2025
Deaths in organised violence (UCDP GED) per 100,000 people (population: UN WPP 2024).
Armed conflict in the country
0 0 none, 1 minor, 2 war latest value, 2025
Strongest armed conflict of the year in which the government or territory of the country is disputed (UCDP/PRIO ACD): 1 = 25-999 battle-related deaths, 2 = war, 1,000 or more. In interstate conflicts every primary party is marked even if the fighting was elsewhere (the USA in Iraq, 2003). Historical states are mapped to present-day countries by territory (USSR, Yugoslavia, South Vietnam and others).
Battle deaths
0 persons a year latest value, 2025
Soldiers and civilians killed in combat in state-based armed conflicts on the territory of the country. 1946-1988: PRIO Battle Deaths (best estimate, else the low one; a conflict of several countries split equally); from 1989: UCDP GED by place of the events. For the same conflicts in 1989-2008 PRIO is 1.6 times UCDP, so the drop in 1989 is partly a change of source. One-sided violence against civilians is not included.
Battle deaths per 100,000
0 per 100,000 people a year latest value, 2025
Battle deaths on the territory of the country (PRIO to 1988, UCDP GED from 1989) per 100,000 people (population: UN WPP 2024), from 1950.
