Variables, and the values they represent, may change over time. If you have used variables in prior year releases, check the ACS product changes webpage for source table changes. If the variable you have been using comes from a table that has changed from the prior year, check the variables list (variables.html) and compare the variable concept and label to be sure you are requesting the correct estimate.
