Economists are banking on 2015 to be the year leading-edge millennials finally start to stream into the housing market. To get an idea of what changes can be expected if the generation does take the plunge, we've gathered data on millennial home buying behavior the past three years in metropolitan statistical areas (MSA) where the 25-34 year-old population is most concentrated.

The only generation defined by the Census Bureau is Baby Boomers, a bracket from 1946 to 1964. In order to get as clear of a picture as possible across both Census and Metrostudy, we used the age range of 25-34 as our leading-edge Millennial age range when pulling data.

To identify MSAs with high shares of leading-edge millennials as a percent of the population, we pulled American Community Survey data and pulled any MSA where millennials accounted for 15 percent or more of the total population.
