Poster: Demographic Multipliers & Planning Ratios

Monday, May 8, 2017 | 1:30 p.m. - 2:30 p.m.

Population and housing changes in the past two decades have made the demographic multipliers published in 2006 outdated. This poster compares current and old multipliers to highlight these changes and show divergent trends between single family and multifamily units. Presenting current multipliers at the local level, the poster illustrates the vast local variations within selected housing types. It compares statewide and geographically specific (at PUMA level) multipliers possible biases of using state average. The poster also discusses alternative samples to meet specific nature of a development, and illustrate the difference between average and marginal figure. The poster outlines the data source (PUMS records of individuals, households and housing units), the methods, and the potential of generating additional planning ratios for planning and estimation of development impact.
