Use of Mammography for Women 40 Years Old and Over

Summary: Percent of women age 40 and older using mammography

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 estimates the next update for these data (2014 or later) in late 2016.
