About Ector County
Ector County is in West Texas and includes Odessa, its county seat. It is closely associated with the Permian Basin region.
Ector and neighboring Midland counties are separate jurisdictions, even though Odessa and Midland form a connected regional corridor. Each county has its own FIPS code, demographic figures, and boundaries.
What is the Ector County FIPS code?
The five-digit county FIPS code for Ector County, Texas, is 48135. The first two digits, 48, identify Texas, while the last three digits, 135, identify Ector County within the state. The county code is distinct from a postal ZIP Code.
FIPS codes are used to connect records across county-level geographic datasets. Use all five digits when searching the Census Bureau’s data. City limits, county boundaries, school districts, and postal ZIP Codes can differ.
County population, income, housing, and land area
The figures above use the American Community Survey 2020-2024 five-year estimates for population, median household income, median owner-occupied home value, median age, and poverty. The survey’s estimates have margins of error. They are not live population counts or listings of current real-estate prices.
The map boundary and land area come from the U.S. Census Bureau’s TIGERweb 2026 county geography. Population density on this page divides the ACS population estimate by mapped land area in square miles. Data vintages and survey methods can affect the comparability of figures.

What happens when a Census data service is unavailable?
The interactive facts or map can show an unavailable message. We do not substitute guessed population or financial values. Review the Data and Methodology page for definitions and data limitations.
