This table provides metadata for the actual indicator available from Vanuatu statistics closest to the corresponding global SDG indicator. Please note that even when the global SDG indicator is fully available from Vanuatuan statistics, this table should be consulted for information on national methodology and other Vanuatu-specific metadata information.
| Definition |
The indicator “Projected Population by Sex, Age Group, and Province” is the estimated number of individuals projected to reside in each province of Vanuatu, disaggregated by sex and 5-year age groups, for each year from 2020 to 2050. |
|---|---|
| Concept |
This indicator is based on the demographic concept of population projections, which are forward-looking estimates derived from the most recent census base population, adjusted using assumptions about future trends in fertility, mortality, and migration. It supports long-term planning, including infrastructure, education, healthcare, and social services, by estimating future population dynamics by region, age, and sex. |
| Disaggregation |
None |
| Rationale |
Population projections provide critical insights for national and provincial policy and planning. Disaggregating the data by age and sex allows for assessment of demographic shifts, ageing trends, youth bulges, and population growth or decline in specific areas. These insights inform targeted investments, especially in health, education, and economic development. |
| Method of Computation |
Method of Computation: Projections are calculated using the cohort-component method, which applies age-specific fertility, mortality, and migration rates to a base year population. Each subsequent year’s population is derived by aging the population forward and applying assumptions for births, deaths, and net migration. Formula: Not applicable — total projected population counts by age group, sex, and province are produced through demographic modelling, not a single formula. |
