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): 6.22 in 1950 → 2.29 in 2023 (−63%). Peak: 6.78 in 1964; the latest value is 66% lower. The trend broke around 1965 and 1974: +0.05 → −0.18 → −0.05 a year.
- Births: 0.85k in 1950 → 0.73k in 2023 (−13%). Peak: 1.89k in 1993; the latest value is 61% lower. The trend broke around 1982 and 1993: +0.01k → +0.07k → −0.04k a year.
- Population: 19k in 1950 → 47.5k in 2023 (+150%). Peak: 57.1k in 2002; the latest value is 17% lower. The trend broke around 1978 and 2000: +0.47k → +1.29k → −0.42k a year.
- Internet: 0% in 1990; no earlier data in this period.
- Urban share: 37.6% in 1960 → 80.5% in 2025 (+43 pp). Thresholds: above 50% since 1968, above 75% since 1990. The trend broke around 2001: direction reversed (+1.2 → −0.36 a year).
- Net migration: on average −0.56k a year in the 1950s, −0.1k a year in the 1960s, −0.35k a year in the 1970s, 0.28k a year in the 1980s, −0.45k a year in the 1990s, −1.38k a year in the 2000s, −1.31k a year in the 2010s, −1.11k a year in the 2020s.
- Life expectancy, men: 57.6 years in 1950 → 70.2 years in 2023 (+13 years). Threshold: above 70 years since 2010. The trend broke around 1958 and 1986: +0.56 → +0.21 → +0.08 a year.
What changed at the same time
- The fastest decline of "Fertility (TFR)" was in 1965–1975: 6.73 → 5.01. Over the same years: births 0.98k → 0.99k; population 23.4k → 29.4k; urban share 45% → 59.2%; net migration −0.09k a year → −0.27k a year; life expectancy, men 64 years → 65.6 years; no data for the others in those years.
- Over the last 10 years (2013–2023): fertility (TFR) 2.93 → 2.29; births 1.12k → 0.73k; population 54k → 47.5k; urban share 85.4% → 81.4%; net migration −1.35k a year → −1.16k a year; life expectancy, men 70.4 years → 70.2 years; no data for the others in those years.
How the indicators relate
- Fertility (TFR) and urban share (1960–2023, 64 years): levels are strongly related, in opposite directions (r = −0.89); year-to-year changes show no reliable link (r = 0.05). This looks like a shared trend: both change over time, but not in step from year to year.
Against other countries
- Order of events: urban majority: 1968; fertility below 3: 2013. Fertility fell below 3 after the urban share passed 50% in 69% of 111 countries where the order is known; median gap 9 years. Fertility fell below 2.1 before half the population went online in 88% of 112 countries where the order is known.
Forecasts vs actual
- Fertility (TFR): past UN projections. The outcome was below the projection in 0 of 1 revisions (2022–2022) and above in 1; median gap +2.4%.
- Fertility (TFR): UN 2024 projection (medium): 2050 — 1.90 (−17% vs 2023), 2100 — 1.74 (−24% vs 2023); low variant for 2100: 1.24.
- Births: past UN projections. The outcome was below the projection in 1 of 1 revisions (2022–2022) and above in none; median gap −1.2%.
- The UN 2022 projection expected today's level (0.73k, 2023) only by 2024: reality is at least 1 year ahead of it.
- Births: UN 2024 projection (medium): 2050 — 0.51k (−30% vs 2023), 2100 — 0.31k (−58% vs 2023); low variant for 2100: 0.11k.
- Population: past UN projections. The outcome was below the projection in 11 of 12 revisions (1998–2022) and above in 1; median gap −44%.
- Population: UN 2024 projection (medium): 2050 — 37.6k (−21% vs 2023), 2100 — 32.3k (−32% vs 2023); low variant for 2100: 20k.
- Why the UN missed the population. The 2022 projection for 2023: 43.9k; the UN's 2024 estimate: 47.5k (+8.2%). Parts of the gap (plus means more people than projected): the starting population +4.2k, births 0, deaths 0 (fewer deaths than expected), migration −0.5k; the largest: the starting population.
- Net migration: UN 2024 projection (medium): 2030 — −0.73k a year, 2050 — −0.2k a year, 2100 — −0.01k a year.
- Life expectancy, men: UN 2024 projection (medium): 2030 — 71 years, 2050 — 73.8 years, 2100 — 81.4 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.

Culture and time
International tourism, receipts (current US$)
22,000,000 current US dollars latest value, 2017
International tourism receipts are expenditures by international inbound visitors, including payments to national carriers for international transport. These receipts include any other prepayment made for goods or services received in the destination country. They also may include receipts from same-day visitors, except when these are important enough to justify separate classification. For some countries they do not include receipts for passenger transport items. Data are in current U.S. dollars.
International tourism, number of arrivals
900 arrivals per year latest value, 2020
International inbound tourists (overnight visitors) are the number of tourists who travel to a country other than that in which they have their usual residence, but outside their usual environment, for a period not exceeding 12 months and whose main purpose in visiting is other than an activity remunerated from within the country visited. When data on number of tourists are not available, the number of visitors, which includes tourists, same-day visitors, cruise passengers, and crew members, is shown instead. Sources and collection methods for arrivals differ across countries. In some cases data are from border statistics (police, immigration, and the like) and supplemented by border surveys. In other cases data are from tourism accommodation establishments. For some countries number of arrivals is limited to arrivals by air and for others to arrivals staying in hotels. Some countries include arrivals of nationals residing abroad while others do not. Caution should thus be used in comparing arrivals across countries. The data on inbound tourists refer to the number of arrivals, not to the number of people traveling. Thus a person who makes several trips to a country during a given period is counted each time as a new arrival.
Land and housing
Agricultural land (% of land area)
14.8 % of land area latest value, 2023
Agricultural land refers to the share of land area that is arable, under permanent crops, and under permanent pastures. Arable land includes land defined by the FAO as land under temporary crops (double-cropped areas are counted once), temporary meadows for mowing or for pasture, land under market or kitchen gardens, and land temporarily fallow. Land abandoned as a result of shifting cultivation is excluded. Land under permanent crops is land cultivated with crops that occupy the land for long periods and need not be replanted after each harvest, such as cocoa, coffee, and rubber. This category includes land under flowering shrubs, fruit trees, nut trees, and vines, but excludes land under trees grown for wood or timber. Permanent pasture is land used for five or more years for forage, including natural and cultivated crops.
Arable land (% of land area)
5.2 % of land area latest value, 2023
Arable land includes land defined by the FAO as land under temporary crops (double-cropped areas are counted once), temporary meadows for mowing or for pasture, land under market or kitchen gardens, and land temporarily fallow. Land abandoned as a result of shifting cultivation is excluded.

Air transport, passengers carried

Air carrier data per country refers to passengers carried by airlines registered in that country regardless of the origin or destination of the passengers.
Fertilizer consumption (kilograms per hectare of arable land)
38.6 kg of nutrients per hectare latest value, 2020
Fertilizer consumption measures the quantity of plant nutrients used per unit of arable land. Fertilizer products cover nitrogenous, potash, and phosphate fertilizers (including ground rock phosphate). Traditional nutrients--animal and plant manures--are not included. For the purpose of data dissemination, FAO has adopted the concept of a calendar year (January to December). Some countries compile fertilizer data on a calendar year basis, while others are on a split-year basis. Arable land includes land defined by the FAO as land under temporary crops (double-cropped areas are counted once), temporary meadows for mowing or for pasture, land under market or kitchen gardens, and land temporarily fallow. Land abandoned as a result of shifting cultivation is excluded.
