Age of Indiana's housing

Half of the housing units in Indiana were built before 1977, by the Census Bureau's ACS 2024 1-year count. 30% were built before 1960, when galvanized supply pipe was common. 23% were built from 1980 to 1999, the two Census decades that overlap the years polybutylene pipe was made. Age alone does not tell you what pipe a house has; a plumber or inspector can.
