Opportunity Insights studied groups of all children born in the US in the same year for each birth year from 1980 to 1991. This grouping included every single US child who had a valid SSN or ITIN (tax identification number) and could be linked to parents with non-negative income.

The incomes of all families in a birth year group are measured when the child is 15-19 and these incomes are averaged. The calculated incomes from all families in the group were arranged from smallest to largest, and divided into five groups of equal size. On the left of the diagram, you can see the relative distribution of Lincoln Technical Institute - Union's students between the family income divided into fifths formed by looking at the entire US group.

In 2014, all people from the same birth year were divided into a new set of five groups that were determined by their individual labor earnings for that year. The students from this birth year who primarily attended Lincoln Technical Institute - Union between the ages of 19 and 22 were divided into these five groups, and the percent in each group is shown on the right of the diagram.

The diagram lets you see the proportion in each original income group who travel to each earnings group, and provides some insight into the likelihood of financial success after attendance.
