Notes:               This data represents the ratio of the mean income for the highest
                     quintile (top 20 percent) of earners divided by the mean income of the
                     lowest quintile (bottom 20 percent) of earners in a particular county.
                     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.

                     Multiyear Estimates" on publication page 13 (file page 19) of the 2018
