Definitions: Economic Ranks for 2012 for each state using a consistent set of economic indicators; namely those used to derive the rank reported in the 2012 KIDS COUNT Data Book.
The Economic Rank for each state was obtained in the following manner. First, we converted the 2010 (or 2008/2009, depending on the indicator) state numerical values for each of the 4 key indicators within each domain into standard scores. We summed those standard scores in each domain to get a total standard score for each state. Finally, we ranked the states on the basis of their total standard score by domain in sequential order from highest/best (1) to lowest/worst (50). Standard scores were derived by subtracting the mean score from the observed score and dividing the amount by the standard deviation for that distribution of scores. All measures were given the same weight in calculating the domain standard score.

Note: Maps use the natural break classification method, which reflects patterns
in the data by dividing the map into naturally occurring groups. Using statistical tools, this method
determines cut-off points for each group by identifying large gaps in data values.
Note: The District of Columbia, Puerto Rico and the U.S. Virgin Islands are
not included in maps and rankings because they are not states and therefore comparisons on many
indicators of child well being are not meaningful.
