  • RE: Adjusting Income in ACS

    The units for the estimate and for the margin of error are the same. For median income, I THINK (please correct this info if it is wrong) that the units are in inflation-adjusted dollars for the ending year of the ACS time period - for example, the 2005…

  • subcategory values not adding to 100%

  • RE: Median Family Income at the tract level: MSA/MD statewide & non-MSA/MD

    Hi Joe and all.  I try not to make pitches for Social Explorer in this group, but we our systems allows one to get a median income for any combined area.  The way it works is that it uses the brackets for income and adds up all of the cases in each bracket…

  • RE: Combining 1-year supplementals

    Hi Lisa -
