                     Multiyear estimates from the American Community Survey (ACS) are
                     "period" estimates derived from a data sample collected over a period
                     of time, as opposed to "point-in-time" estimates such as those from
                     past decennial censuses. ACS 5-year estimate includes data collected
                     over a 60-month period. The date of the data is the end of the 5-year
                     period. For example, a value dated 2014 represents data from 2010 to
                     2014. However, they do not describe any specific day, month, or year
                     within that time period.
                     
                     Multiyear estimates require some considerations that single-year
                     estimates do not. For example, multiyear estimates released in
                     consecutive years consist mostly of overlapping years and shared data.
                     The 2010-2014 ACS 5-year estimates share sample data from 2011 through
                     2014 with the 2011-2015 ACS 5-year estimates. Because of this overlap,
                     users should use extreme caution in making comparisons with
                     consecutive years of multiyear estimates.
