City time series
Phoenix's urban expansion: 1975–2025, built-up area 1.9×
- United States
- GHSL epochs 1975–2025
At a glance
- Phoenix's built-up area grew from about 190 km² in 1975 to 355 km² in 2025 — 1.9× the 1975 footprint, or +1.3% per year compounded.
- Over the same window the urban centre's population 4.4×, reaching about 2.6M by 2025.
- The current footprint of 355 km² is equivalent to about 104 Central Parks.
Key growth numbers
- Built-up area 1.9× +1.3% per year since 1975
- Population 4.4× about 2.6M in 2025
- GHSL epochs 11 five-year steps, no interpolation

Method & data
All numbers come from the GHS Urban Centre Database (GHSL): the European Commission's Joint Research Centre publishes, for every urban centre on Earth, the total built-up area and resident population on five-year epochs from 1975 to 2025.
An epoch is a full mapping pass, not an estimate for that calendar year; a metric the source does not report for an epoch is shown as missing — values are never interpolated or extrapolated between epochs.
The numbers stay inside the GHSL Urban Centre boundary — a stable, data-derived footprint of the contiguous built-up core, not an administrative city limit; figures are therefore not comparable to city-proper census counts.
A night-lights curve (VIIRS) is planned as a second series and is not part of this page yet; the epoch table above is the complete published dataset for this city.
Frequently asked questions
How much has Phoenix grown between 1975 and 2025?
