How the Market Opportunity Score uses these numbers
The Market Opportunity Score (0-100) compresses the demographic profile into one agency-prospecting question: does this market support local-services agency retainers? Higher household income lifts the ceiling on what businesses here can afford to spend on marketing. Higher owner-occupancy correlates with longer customer tenure, which correlates with higher CLV — which means the local plumber here can spend more per acquisition.
Median home value and median year-built layer in housing-stock signals: older homes in expensive markets generate more home-services demand per capita than newer homes in equivalent markets. Population sets the absolute size of the addressable customer base — but a low-population market with the right income profile can outperform a high-population market without it.
