Discover Waterloo
The U.S. Census Bureau lists Waterloo town as an incorporated place. Its Vintage 2025 series estimates a resident population of 183 on July 1, 2025. In this collection, a small place means one with a 2025 estimate of 10,000 or fewer; that is a selection threshold, not a separate legal category. The figure describes the Census place geography, not everyone in a surrounding ZIP code or neighboring unincorporated area.

Within Alabama, Waterloo town ranks 53 among incorporated places whose 2025 estimates are at or below 10,000, ordered from smallest upward. This is a within-state population comparison, not a ranking of quality, popularity, or amenities. For a meaningful comparison, use the same Census vintage, reference year, and geographic boundaries. The Census name is retained here so readers can distinguish the official estimate record from the postal-city label used by this directory.
