Multiple listing services are categorized into nine US Census regions, with the MLSs on each regional page organized by subscriber tiers based on year-end totals as of Dec. 31, 2025.

A regional perspective offers an appraisal of geographic patterns — including concentration of subscribers, relative market scale, and recent consolidation — and illuminates how adjacent states share or diverge in MLS structure and capacity. These pages are intended to supply comparative, regionally consistent context while aligning with the Almanac’s tiered reporting approach (subscriber ranges rather than precise ranked totals), which was adopted to balance analytic clarity with reporting constraints.
