Income Range (in dollars)Number of Individuals (in millions) 0 - 499920.353 5000 - 999921.476 10000 - 1499921.981 15000 - 1999918.801 20000 - 2499917.742 25000 - 2999914.941 30000 - 3499914.078 35000 - 3999911.895 40000 - 4499910.447 45000 - 499997.994 50000 - 549998.963 55000 - 599995.136 60000 - 649995.921 65000 - 699993.909 70000 - 749993.961 75000 - 799993.139 80000 - 849992.886 85000 - 899991.806 90000 - 949991.910 95000 - 999991.278 100000+13.215

11. Histogram Histogram: A bar graph for which the categories are individual numbers or equal length intervals of numbers.

12. Line Graph Line Graph: A graph in which adjacent data points are connected by a line. Appropriate for displaying “continuously varying” data.

13. Applying Percentiles & Median From examining this graph, we can easily see that the average (specifically, the median) income of individuals in the USA in 2008 was about $25,000, and that an income of $75,000 per year would place the earner at approximately the 90th percentile.

17. Using Census in Business  There are many ways different businesses use the data of the US Census  To study their industry  Gauge the competition  Calculate Market Share  Locate business in an area  Expand their business to a new market
