Our Mission
City Population Data was built to make urban demographic information accessible, organized, and easy to explore. We believe population data should be freely available to everyone — researchers, students, journalists, urban planners, and the simply curious.
Every page on our site is designed to load fast, work on any device, and present data in a clear, useful format. We combine raw numbers with context: rankings, geographic information, comparisons, and related cities to help you understand the bigger picture.
Data Sources & Methodology
Our population data is compiled from multiple authoritative sources:
- National census bureaus — official population counts conducted by government statistical agencies
- United Nations population estimates — standardized demographic projections and estimates
- Public demographic databases — verified open data sources including GeoNames and similar repositories
We cross-reference multiple sources when available and clearly indicate the year of each data point. Population figures represent city proper populations unless otherwise noted.
