This dataset contains information about Colorado State infant mortality rate in 2011.
The infant mortality rate is defined as infant deaths under 1 year of age per 1,000 live births. Sixteen census tract records with no data values were added to the data set for the purpose of getting better visualization. Data summarized from individual-level to the census tract. Data with counts 3 or less are suppressed, so 0 means 3 or less instances for both counts and their respective percentages.
