This database provides data on women's use of mammography based on a wide variety of characteristics (race, age, insurance status, education, disability, and year).  Data reflect the percentage of women who had a mammogram in the past two years and are based on household interviews of a sample of the civilian non-institutionalized population.  Data are unavailable for 1988-1989, 1992, 1995-1997, 2001-2002, 2004, 2006-2007, and 2009.  

NA indicates data that are not available or have a Relative Standard Error (RSE) or more than 20%.  These data are considered unreliable.  RSE is calculated by dividing the standard error of the estimate by the estimate itself, then multiplying that result by 100.  RSE is expressed as a percent of the estimate.  For example, if the estimate of women receiving a mammogram is 20 percent and the standard error of the estimate is 5 percent, the RSE of the estimate = (5/20) * 100, or 5 percent. Data starting in 1997 are not strictly comparable with data for earlier years due to the 1997 questionnaire.  See also detailed background.


The CDC has not updated this database beyond 2010.  Previously, the CDC estimated the next update in late 2016.  We will post new data if and when the data become available.
