Description

BUILTYR2 reports the decade in which the structure was built.

This variable is particularly susceptible to response errors and non-reporting since respondents often relied on their memory or estimation to arrive at an answer.

Comparability

This variable is comparable across the 2000-onward ACS samples and the 2005-onward PRCS samples. A similar variable, BUILTYR, is available in the U.S. 1960-2000 census samples, the 1970-2000 Puerto Rican census samples and the 2000 ACS.

Editing Procedure

BUILTYR2 and MOVEDIN
ACS ACS Years: 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016
ACS editing procedure:
If a vacant unit (VACANCY) has a value for when the unit was built or when the reference person moved into the unit (BUILTYR2, MOVEDIN), it will be replaced with a "Not in universe" value.
If the year the reference person moved into a unit (MOVEDIN) is after the survey year (YEAR), it will be replaced with the survey year. When this happens, the flag (QMOVEDIN) will indicate the value was allocated.
If the year the reference person moved into a unit (MOVEDIN) is before when the reference person was born (BIRTHYR) or entered the U.S. (YRIMMIG), it will be replaced with a blank value.
If the year the reference person moved into a unit (MOVEDIN) is before when unit was built (BUILTYR2), BUILTYR2 will be replaced with a blank value. If the year the reference person moved into a unit (MOVEDIN) is less than 1800 and the year built is 1939 or earlier, the BUILTYR2 will be replaced with a blank value.
If the year the reference person moved into a unit (MOVEDIN) and the year the unit was built (BUILTYR2) are both blank, they will be allocated jointly from another unit similar building type (UNITSSTR). When this happens, the flag (QMOVEDIN, QBUILTY2) will indicate the value was allocated.
If the year the reference person moved into a unit (MOVEDIN) is blank, it will be allocated from another unit with similar value for OWNERSHP (2008 and later, also BUILTYR2). If the allocated value of MOVEDIN is before when the unit was built, the allocated value will be discarded. Four attempts will be made to allocate the value of MOVEDIN. If the four attempts fail, it will be left blank. When MOVEDIN is allocated, the flag (QMOVEDIN) will indicate this.
If the year the unit was built (BUITLYR2) is blank, it will be allocated from another unit with a similar building type (UNITSSTR). If the allocated value of BUILTYR2 is after the reference person moved into the unit (MOVEDIN), the allocated value will be discarded. Four attempts will be made to allocate the value of BUILTYR2. If the four attempts fail, it will be allocated as the year the reference person moved in. When BUILTYR2 is allocated, the flag (QBUILTY2) will indicate this.
Beginning in 2008, there was a write in box to specify the year if the house was built after 2000. If 2000 or later is selected, but there is no year in the write in box, it will be allocated. The allocated value is drawn from another unit built after 2000 with a similar building type (UNITSSTR).
IPUMS editing procedure:
The question on the form asks in what year the person had moved into this house, apartment, or mobile home. The IPUMS recodes the original categories into lengths of time to increase comparability.
