How many counties does New Mexico have?
New Mexico has 33 counties covering 121,298 square miles and roughly 2,124,610 residents. The state was admitted to the Union in 1912 as the 47th state, and the current county boundaries reflect more than a century of administrative subdivision.
The largest county by land area is Catron County at 6,924 square miles, home to about 3,743 residents. The most populous is Bernalillo County with approximately 671,328 residents — a density of about 578 people per square mile.
At the other end of the scale, Harding County has only about 1,442 residents.
New Mexico’s capital is Santa Fe, while the largest city is Albuquerque — a common pattern in the United States, where many states placed their capitals in smaller, more central towns rather than their largest commercial hubs.
