Where a Local Business Has the Most to Write About: The Local Content Opportunity Index
Every county on this site gets a score from 0 to 100 for how much material a local business has and how many of its buyers research before they call. Towns, trades whose customers read first, new businesses, household income and new homes all feed it. It counts businesses and households, not visitors or leads, and it uses only public Census data.

LCOI is a weighted average of five county percentiles: 30% the mean percentile of locations per 10,000 residents across seven research-heavy categories, 30% median household income, 15% places with 2,500+ residents, 15% new-home permits per 10,000 residents and 10% growth in employer locations since 2017. Components a county lacks are dropped and the rest re-weighted. Percentiles compare each county with all U.S. counties of 20,000+ residents. Connecticut uses historic counties and 2021 data because newer Census files use planning regions. Data built October 20, 2026. Method
