What is NVI?

The Neighborhood Vitality Index is a 0–100 score that measures how healthy and thriving a census tract is — based entirely on US Census Bureau data that you control.

🧮 The Default NVI Formula

The NVI uses 10 key metrics weighted by importance. Users can customize which metrics are included and how heavily they are weighted.

Median Household Income

Higher household income signals a stronger local economy and greater purchasing power.

Median Home Value

Property values reflect market confidence and investment activity.

Homeownership Rate

Owner-occupied housing percentage. Homeowners tend to invest more in their neighborhoods, driving stability.

Low Poverty Rate

Lower poverty rates score higher. Measures economic health of the population.

Public Transit Access

Percentage of workers commuting via public transit. Higher transit access signals better connectivity.

Low Unemployment

Employment rate as a share of the labor force. Lower unemployment means a stronger local job market.

Low Vacancy Rate

Vacant housing units as percentage of total. High vacancy signals declining demand.

Family Households %

Family households as percentage of total. More families indicate community stability.

Education Level

Educational attainment rate. Higher education correlates with economic mobility.

Housing Stability

Estimated housing stability based on tenure patterns. Long-term residents indicate neighborhood commitment.

🚧 Additional Metrics Available

Users can enable these metrics in the Customize NVI panel.

Population Density

Population relative to area — signals activity and demand

Rent Affordability

Rent as percentage of household income — lower = more affordable

Housing Age

Median year structures were built — newer = better condition

Vehicle Access

Vehicle ownership as economic mobility proxy

Graduate Degrees %

Master's, professional, or doctoral degrees
