How fast is Leander growing?

In short

• About 91,100 people lived in Leander on July 1, 2025, says the U.S. Census Bureau.¹
• That is up about 54% since the 2020 census, from about 59,200 (our math).¹²
• In the last year the city added about 3,450 people, close to 4% (our math).¹²

Numbers marked “our math” are our estimates, not official figures. The notes show the inputs and the steps.

How it works

• The Census Bureau counts everyone every 10 years. In between, it makes yearly estimates for each city as of July 1.¹
• City estimates follow city limits. When a city annexes land, people living there are added.¹
• Each release can revise past years, so older numbers may change.¹

• Leander year by year (July 1): 60,868 in 2020; 67,099 in 2021; 74,584 in 2022; 80,540 in 2023; 87,680 in 2024; 91,132 in 2025.¹
• About 1 in 8 Williamson County residents now lives in Leander (our math). A small part of Leander is in Travis County.¹²

The other side

• The city’s own number is higher. The city’s 2025 audit report uses 92,872, about 1,740 more than the Census estimate (our math).² The audit does not say how the city got its number.
• Cedar Park’s slow growth is not a sign of trouble by itself. It has little open land left, so it cannot grow as fast.
• Estimates can be wrong. The true number will not be known until the 2030 census.

Questions to ask

• Which population number does the city use for its budget and plans, and why?
• How much of recent growth came from annexed land, by the city’s count?

Changes to this page

• Nov. 2, 2026: We removed an unsourced reason for why the city’s population number is higher.
• Nov. 2, 2026: Rewrote the questions to ask so each is open, neutral and addressed to the public body.

What we still don’t know

• How many people live just outside city limits and use city roads and parks.
• The 2026 estimate.

2. Our math. 91,132 ÷ 59,235 = +53.8%; 91,132 − 87,680 = 3,452; 3,452 ÷ 87,680 = +3.9%; Williamson County July 2025 estimate 752,827 (Census 2025 county file), 91,132 ÷ 752,827 = 12.1%; city 2025 audit population 92,872 (statistical section, Saved copy), 92,872 − 91,132 = 1,740.
