With a current population of approximately 10,000, Csömör's modest size is tied to its agricultural past and relatively small economic base, which has made it less attractive for younger generations seeking career opportunities in larger cities.

The ageing population trend in Csömör can be attributed to younger residents moving to Budapest or other urban centers for education and work, leaving behind an older demographic.

Despite its peaceful environment and proximity to the capital, Csömör’s lack of significant industrial or technological development has prevented substantial population growth over the years.
