Interpretation Data ;

The population pyramid graph above illustrates the population distribution in Jakarta in 2022. The 0-4 age group has a larger population compared to several age groups above it. The 30-34 age group has a slightly larger male population (388,746) than the female population (431,768). For the 65+ age group, the male and female populations are relatively balanced with slightly more females.

This population pyramid shows a young population structure, with a wider base in the younger age group (0-19 years) and then starting to narrow in the older age group. This is an indication that Jakarta still has a fairly young population with the potential for a large population in the future.
