Just to underscore the effect of age (or rather, the combination of education, experience and work status) upon individual income in the U.S., we came up with the following chart that shows how income within a given range is distributed among individuals within a given age range on a percentagewise basis:
In the chart above, the relative concentration of U.S. individuals by age for a given income range is indicated by the relative width of the corresponding age strata. Here, a wider band indicates that the indicated age bracket has a higher percentage of members within the indicated income range.
At the low end of the income scale, we find that those Age 15-24 make up the largest share, followed by those Age 65-74. This may be explained by those in the Age 15-24 group largely participating in educational pursuits (high school, college) and their low levels of experience and training for those participating in the workforce. For those in the Age 65-74 bracket, retirement accounts for the relatively higher level of low income among this age group.
As income increases, we find that as age increases, so does the relative share of income earned. In other words, the older the American, the more money they make, at least through their prime working years from Age 25-64!

Welcome to the blogosphere's toolchest! Here, unlike other blogs dedicated to analyzing current events, we create easy-to-use, simple tools to do the math related to them so you can get in on the action too!

Political Calculations' Recession Probability Track shows the probability that the U.S. economy will be in recession 12 months from the indicated date (shown in red) while revealing the probability trend over the past four years.
Previously, the probability of recession peaked at 50% on 4 April 2007, which means that March-April 2008 was the most likely period in which the NBER would have found the U.S. to be in recession.
As it happens, they almost did. The NBER instead chose December 2007 as the beginning month of the most recent recession (we had found a 46% probability for a recession beginning in that month!)
Political Calculations is also the online home of On the Moneyed Midways (aka OMM), a review of the best posts contributed to the week's best business and money-related blog carnivals. More than that, we also name one post in each edition as being The Best Post of the Week, Anywhere! and at the end of each year, we name The Best Post of the Year, Anywhere! as well as identifying the best blogs we found during the course of the year!
