Some time ago in our post about the fastest-growing industries, we found that the only industry that didn’t see a decline in employment numbers in 2008 was healthcare. Thanks to this fact, the industry has seen the largest growth since 2000, creating almost 30 percent more jobs by 2012.

One particularly interesting thing you can learn from the County Business Patterns data is the distribution of establishments by size. Of course, such distribution would significantly depend on the industry — you are unlikely to find any small businesses among hospitals or schools. But many types of businesses, like graphic or interior design services, are usually very small.

Early delinquencies are more likely for higher income borrowers

Any lending (and especially peer-to-peer) is inherently associated with substantial financial risks.  But sometimes it looks like the borrower didn’t make any serious effort to repay the loan, defaulting just months after the origination date.

Today we will take a look at the number of early delinquencies among all loans issued through Prosper, one of the two major peer-to-peer lending marketplaces in the U.S. For the purpose of this post, we consider a loan to end with an early delinquency if it was charged off less than one year after the origination date.

Occupational standing of different demographics

The Num-Powers-Boyd score measures occupational status based on median education levels and median incomes of individuals. An intuitive interpretation of the score of an occupation is the percentage of the population having an occupation with education and income levels below that occupation. This score weights education and income contribution equally. Although the use of such indices is still a topic of discussion among professional sociologists, this simple and clear interpretation can be understood by everyone.

In a previous post, we used this measure to examine occupation rankings through time. Today we will look at the scores of different demographic groups. This time we also use data provided by Minnesota Population Center and IPUMS.

Bicycling and Walking to Work in the United States

Pavel Prikhodko, Ph.D. Machine Learning

According to the United States Census Bureau data for 2008-2012, more than half of all Americans commute to work every working day. Personal cars and public transportation are not the only modes of commuting, but they are the most popular. Year by year, walking and riding a bicycle are becoming more and more popular, and the corresponding infrastructure is developing rapidly. One can agree that walking and bicycling have a few advantages over motorized travel. They are healthier, ecologically pure and require less expensive infrastructure than other commuting modes. Of course, the distribution of the number of pedestrians and bicyclists in the states is not uniform. The city with the highest percentage of walkers is Ithaca, NY. Portland, OR has the highest percentage of bicyclists.

For most young people, reaching adulthood comes with leaving their parents residence and starting to live on their own.  However, due to various circumstances, young adults may remain living with parents for a longer period. In this post, we examine ACS data provided by the Census and IPUMS to see how housing arrangements of young adults have changed over the decades.
