Appendix A. Methodological Notes <br />This study and the methodology of this analysis was designed by the Next Practice Ltd (TNP). The <br />TNP methodology incorporated data generated by TNP through customized use of the Nielsen Claritas <br />retail analysis model, which is data copyrighted by The Nielsen Company. The downtown scenarios were <br />generated using a customized retail scenario model for downtown Santa Ana that was created by TNP. <br />MASdata provided local research services for both the quantitative and qualitative aspects of the study, <br />including the 40 in -depth consumer interviews. TNP entered and analyzed the qualitative interview data <br />using TNP's User Optimization tool. <br />Al. The Study Area <br />The first methodological task in a study of this nature is to define the geographical areas that serve as the <br />consumer catchment areas for different consumer segments. Within the constraints of the study's terms <br />of reference, two different data sets and sources had to be used to define the precise areas of `downtown <br />Santa Ana' and `central Santa Ana.' Data on household characteristics, such as income, disposable <br />income, ethnic background, educational background, employment and commuting patterns were taken <br />from the U.S. Census Bureau, American Community Survey (ACS). This data is available by census tract. <br />To secure data on the commercial business mix, retail and services expenditures, and sales at the scale of <br />part of a municipality, we relied upon the Nielsen Claritas data and model. The Nielsen Claritas model <br />combines demand data from the U.S. Bureau of Labor Statistics Consumer Expenditure Survey and <br />supply data from the U.S. Census of Retail Trade. This data is available by radial areas, the radii of which <br />have been defined byTNRTNP also secured data from the California Board of Equalization for this <br />purpose. <br />Downtown Santa Ana <br />Within this context, TNP defined `downtown Santa Ana' in two ways. For purposes of demographic and <br />household profiles, the primary historical downtown/civic center area is Census Tract 750.02, Orange <br />County, California. For purposes of retail and services trade data, the primary downtown area is defined <br />as the area of 0.5 mile radius from the intersection of 4th Street and N. Main Street. This area extends <br />to Mortimer Street to the east, 8th Street to the north, Ross Street to the west, and Walnut Street to the <br />south. The distance of 0.5 mile is used to represent the walking catchment area whose longest distance is <br />the 1.0 mile diameter of the circle. <br />An extended downtown/civic center area was also considered to generate and analyze data on <br />commercial business mix, retail and services expenditures and sales. This is the circular area of 1.0 mile <br />radius, whose center is the intersection of 4th Street and N. Main Street. This area extends to Garfield <br />Street to the east, Washington Street to the north, Flower Street to the west, and Camile Street to the <br />south. The distance of 1.0 mile is used to represent a catchment that includes walking customers from <br />a distance of 1.0 mile and bicycling customers from a distance of up to the 2.0 miles diameter of the <br />circular. <br />Unless otherwise indicated, the retail and services sales figures presented in the report and scenarios refer <br />to the `downtown' as the 0.5 mile radius area. <br />The h_ ,xt Practice WS—B-30 ta Ana Wellness District: A study of demand and supply for wellness goods and services <br />
