How many people live in Belgium and how old they are determines how many schools, homes, care services and pensions are needed. The population changes through births and deaths, and through people moving to or leaving Belgium. Here you can see both.
A government is never the only cause of how a figure develops. Many figures only respond to policy years later, and they also depend on the world economy, European rules and the policies of the regions and communities.
