Yokohama City Future Population Estimation
Last update date April 10, 2024
Future Population Estimation of Yokohama
Estimation period
Based on 2020 as the base time, estimates were made for each year until 2070.
Estimation method
Cohort Factor Method
The cohort factor method estimates the future population by assuming future values for each cohort (group born in the same year or the same period) for births, deaths, transfers, and out-migration, which are the factors of population increase or decrease.
Furthermore, in this estimation, we set provisional values for future births and deaths (in cases with many births and fewer deaths) and low levels (in cases with few births and deaths) and made high-level estimates.
