Learn more about City Population Data — our mission, data sources, and the team behind the project.

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.

Technology

City Population Data is built with performance and accessibility as core priorities:

  • Optimized for speed — all pages score 95+ on Google PageSpeed Insights
  • Fully responsive design that works on desktop, tablet, and mobile devices
  • Accessible to screen readers and keyboard navigation (WCAG compliant)
  • Served through a global CDN for fast loading times worldwide
  • Structured data (JSON-LD) for rich search engine results
