Becoming a doctor in the U.S. is commonly associated with respect, good pay and social status, and pursuing a degree in medicine is a promising career choice for many Americans. However, students must choose from a wide range of specializations in the later stages of their education.

To become a practicing physician in the U.S., one has to receive a medical education here or be a foreign graduate in medical studies. In the latter case, one also has to receive a license to practice in the U.S. Three organizations collectively oversee the certification of medical professionals: the American Medical Association, the American Osteopathic Association and the American Association of Physician Specialists.

When planning a trip around the U.S. or abroad, we often consider airlines as a method of transportation. Everyone has their own requirements when choosing an airline: Seat availability, ticket price, leg room and food choices often play a major role. If you are planning a business trip, things like punctuality and proper baggage handling become more important.

“Game of Thrones” is a fantasy drama TV series on the station HBO. It is based on author George R.R. Martin’s series of fantasy novels, “A Song of Ice and Fire.” While the first episode of the TV series aired in 2011, the first book of the series came out in 1996.

In this post, we will combine data from the American Time Use survey and Current Population Survey to see how time use patterns change with geographic location. We used 11 years of ATUS data (2003-2014) and the corresponding CPS data about the respondent’s state of residence. The American Time Use survey classifies daily activities into 431 detailed categories. For this post, we selected only those having a participation rate of at least 30 percent in each state. The top activities included sleeping, washing and dressing, food preparation, work, eating and watching television.

Are business industries sensitive to climate?

The geographic properties of an area often dictate the type of businesses that can locate there. For example, you can’t have an inland naval base. Farms and agriculture, in general, are less likely to prosper on rocky mountains than on sunny plains. But today, with all the technological advancements we have, many jobs in intellectual labor, including IT and finance, hi-tech manufacturing and other new industries seem less likely to depend on climatic features.

To summarize climate features of a territory, we used the existing climate zones classification prepared by the U.S. Department of Energy. Each county is assigned to one of eight climate zones. Definitions of these zones depend not on temperatures, but rather on accumulated heat (the unit is called “degree-days”). Zone 1 has the warmest climate, while zone 8 has the coldest – in the U.S., only certain parts of Alaska belong to this climate zone. We present a map of the climate zones below; you can click to zoom in on a state of interest.

Gross domestic product is commonly used to measure the economic performance of a country. GDP equals the value of all the goods and services produced in the economy minus the value of any goods or services used during the production process. Another name for this quantity is “value added.” Recently, the Bureau of Economic Analysis released data on GDP by industry for 2016. Today we will look at this data to see different industries’ contributions to the U.S. economy’s growth in the last year.

The United States Bureau of Economic Analysis provides a lot of quantitative information on the country’s economic activities. The Bureau’s Industry Economic Program prepares one particularly interesting type of data: commodity input-output tables. These tables show how industries interact to provide input to and take output from one another.
