The colon is used to separate two independent clauses when the second explains or illustrates the first. In such usage, the colon functions in much the same way as the semicolon. As with the semicolon, do not capitalize the first word after the colon unless the word is ordinarily capitalized.
The median household income in 2014 was $53,719, which means that half of American households make less than this amount, and half make more. Since the median is significantly below the average, it tells us that there are more households with below-average household income than above-average, and that the average is distorted by a small percentage of high-income households.
Middle Class Average Income Range: $36,000 â $57,657 On a narrow view, a middle class family is said to have a mean average household income of $46,829 on a yearly basis. The numbers reflected on the 2010 Census showed that middle class average yearly income range from $36,000 â $57,657. Such figures fall on the third quintile. The Census Bureau uses âquintilesâ to divide household incomes and this can serve as the basis to determine if you indeed belong to the middle class families.
