Table B19049 MEDIAN HOUSEHOLD INCOME IN THE PAST 12 MONTHS (IN 2015 INFLATION-ADJUSTED DOLLARS) BY AGE OF HOUSEHOLDER

Using FactFinder to examine this table in the 2015 5YR data.

Can anyone explain why only 60 out of 67 counties in Florida show up? 

Only table I have come across that does not have all 67 counties.
