In 2016 the Behavioral Risk Factor Surveillance System (BRFSS) disability definition changed to include anyone who reports serious difficulty seeing, hearing, walking or climbing stairs, dressing or bathing, concentrating or making decisions, or who, because of a physical, mental, or emotional condition has difficulty doing errands alone. Previously the BRFSS defined disability as activity limitations due to physical, emotional or mental problems OR any health problem that requires use of special equipment. While the percent of Vermonters reporting a disability was similar between the 2015 and 2016 definitions, comparisons should not be made to prior years.
Due to BRFSS weighting methodology changes beginning in 2011, comparisons between data collected in 2011 and later and that from 2010 and earlier should be made with caution. Differences between data from 2011 forward and earlier years may be due to methodological changes, rather than changes in opinion or behavior.
