Using Census data, the Low English Proficiency Populations Index shows Census blocks classified into five categories based on the population of persons with low English proficiency as a percentage of the total population. Persons with low English proficiency are persons identified by the Census as speaking English less than “very well.” An index score of five indicates a higher density of persons with low English proficiency.
