Federal Transit Administration (FTA)• States “Transit providers shall prepare demographic and service profile maps and

charts after each decennial census and prior to proposed service reductions or eliminations.”

• Title VI Program Plan: must be submitted to FTA every three years and must be approved by board of directors or appropriate governing entity prior to submission to FTA.

• Transit providers that have implemented or will implement a New Start, Small Start, or other new fixed guideway capital project shall conduct a service and fare equity analysis.

• Require maps displaying transit base data, demographic profile data and transit facilities

• Demographics– Maps and Charts– Low Income Areas

• Aerial Photo (Land Use)• Minority Population Density• Population + Employment Density

– Minority Population Area• Aerial Photo (Land Use)• Low Income Household Density• Population + Employment Density

– Limited English Proficiency (LEP)• Fare Policy• Service Changes• Service Standards

– Headways– On-time Performance– Service Availability– Transit Amenities– Vehicle Assignments

Base Spatial Data

• District Boundary• Route Lines• Transit Facilities

– Administrative– Maintenance– Park-n-Rides– Rail Stations– Shelters– Transfer Stations

• Other– Business Districts– Hospitals– Schools

Census Data• Census.gov

– American FactFinder• factfinder2.census.gov

• Low Income Households Density– FTA “any group of households whose

income is <=150% of the household sizepoverty guidelines for the average householdsize of that census tract”

– Calculations• AVERAGE_HH_SIZE: TOTAL_POP / HOUSEHOLDS• HH_LESS_25: [HH_LESS_10] + [HH_10_15] + [HH_15_25]• HH_LESS_35: [HH_LESS_25] + [HH_25_35]• HH_LESS_50: [HH_LESS_35] + [HH_35_50]• HH_LESS_75: [HH_LESS_50] + [HH_50_75]• LOW_INC_HH:

– IF [AVERAGE_HH_SIZE] <= 2 THEN [HH_LESS_25]– IF [AVERAGE_HH_SIZE] > 2 AND <= 4 THEN [HH_LESS_35]– IF [AVERAGE_HH_SIZE] > 4 AND <= 6 THEN [HH_LESS_50]– IF [AVERAGE_HH_SIZE] > 6 THEN [HH_LESS_75]

• LOW_INC_HH_PCT: [LOW_INC_HH] / [HOUSEHOLDS]

• Minority Population Density– Total Population - White Population = Minority Population– Minority Population / Total Population = Minority Population Density

Demographic Analysis

“Polygon Overlay Tool”

• Spatial Area Ratios– Ratios applied to

demographic fields

Tables• Regional Population Data (RTD Service

Area)– Total Population of Service Area– Minority Population– Minority Population Percentage– Total Households– Low-Income Households– Low-Income Households Percentage

• Affected Census Tracts– Route/Service

• Bus• Call-n-Ride• Light Rail

– Service Change Type• Current Route• Discontinued Service• New Route

– Total Population Affected Tracts– Total Minority Population in Affected

Tracts– Minority Population Percentage– Total Households Affected Tracts– Total Low-Income Households in

Affected Tracts– Low-Income Households Percentage– Spatial Data Type Used

Summary

• Title VI Reporting– Responsibilites– GIS– FTA
