Description

DIFFCARE indicates whether respondents have any physical or mental health condition that has lasted at least 6 months and makes it difficult for them to take care of their own personal needs, such as bathing, dressing, or getting around inside the home. This does not include temporary health conditions, such as broken bones or pregnancies.

Comparability

Apart from universe differences, there are slight changes to the question wording. Most dramatically, the 2008 ACS/PRCS dropped the stipulation that the health condition have lasted for at least six months.

User Caution: Researchers utilizing the disability variables in the ACS should be aware of changes to the ACS questionnaire between 2002 and 2003. Due to these changes, it may be impossible to distinguish between actual differences in disability rates between 2002 and 2003 and differences attributable to changes in the questionnaire. See this Census Bureau working paper for more information: Disability Data From the American Community Survey: A Brief Examination of the Effects of Question Redesign in 2003 . Users should also exercise caution in comparing rates between 2007 and 2008, as the questionnaire changed in both wording and structure.

Editing Procedure

DIFFREM (Cognitive difficulty)
DIFFPHYS (Ambulatory difficulty)
DIFFMOB (Independent living difficulty)
DIFFSENS (Vision or hearing difficulty)
DIFFCARE (Self-care difficulty)
DISABWRK (Work disability)
DIFFEYE (Vision difficulty)
DIFFHEAR (Hearing difficulty)
ACS Years: 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015
ACS editing procedure:
Note: DIFFEYE and DIFFHEAR were added in 2008; prior to 2008 they were asked together in DIFFSENS. DISABWRK was not asked in 2008 or later.
If a person has a "Blank, Don't Know, Refused, or Bad Value" for DIFFEYE, DIFFHEAR, DIFFREM, DIFFPHYS, DIFFMOB, DIFFSENS, DIFFCARE, or DISABWRK it will be allocated. If the person is under 16 (15 starting in 2008), the allocated value will be drawn from other respondents of a similar age and sex. If the person is 16 to 29 (15 to 29 starting in 2008), the allocated values will be drawn from other respondents with the same sex, employment status, and school enrollment status. For those 30 to 64, the allocated values will be drawn from other respondents with the same sex, employment status, and age group (30 to 39, 40 to 49, and 50 to 64). For those 65 and older, the allocated values will be drawn from other respondents with the same sex and age group (65 to 74, 75 to 84, and 85+). The flag variables will show when a value is allocated (QDIFHEAR, QDIFEYE, QDIFREM, QDIFPHYS, QDIFMOB, QDIFSENS, QDIFCARE, QDISABWR)
If a person is under 5 years old, DIFFREM, DIFFPHYS, DIFFSENS, and DIFFCARE will be replaced with a "Not in universe" values. If a person is under 16, DIFFMOB and DISABWRK will be replaced with "Not in universe."
