Definition: Percentage of people aged 65 and over who were ever told by a doctor they had diabetes, three-year average
Notes: The data are from Behavioral Risk Factor Surveillance Survey (BRFSS). Respondents were asked the question: "Have you ever been told by a doctor that you have diabetes?" Percentage is a 3-year average, which helps to reduce the year-to-year fluctuation due to small numbers. Percentage is reported under the year at the midpoint of the 3-year period. National data is the median of the 50 states and the District of Columbia.
