On June 26, 2015, The United States Supreme Court ruled in the famous Obergefell v. Hodges case that state-level bans on same-sex marriage are unconstitutional.

This decision effectively made same-sex marriage legal in all U.S. states and Washington, D.C., as well as all U.S. territories except for American Samoa, but not on all Indian lands. Prior to the decision, many states already recognized same-sex relationships but were not obligated to recognize marriages registered in other jurisdictions.

The American Community Survey began providing data on same-sex married couples in 2013. This data, however, is limited to the householder and his or her spouse. In today’s post, we will explore the ACS data from the Census Bureau spanning years 2013-2015, focusing on same-sex married couples.

Are business industries sensitive to climate?

The geographic properties of an area often dictate the type of businesses that can be located there. For example, you can’t have an inland naval base. Farms and agriculture in general are less likely to prosper on rocky mountains that 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.

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 were sleeping, washing and dressing, food preparation, work, eating and watching television.

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 interesting type of data: commodity input-output tables. These tables show how industries interact to provide input to and take output from one another.

Preamble

Protecting your personal data on the web was always a big concern. Right now, a lot of sensitive information about an individual can be accessed using the internet, like social media and online banking services. Your passwords become the first line of defense against cyber-criminals of any kind. Having a good password has become a must. Most people don’t even think about going out without locking the house, and many will not leave a car window down in an unknown neighborhood. The situation is very different on the internet, however; many people still use “qwerty” or “123456” as their password, and it is often written down on a piece of paper stored near their PC.

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.

Gross output represents the market value of all services and goods produced in a nation’s economy. This value differs slightly from gross domestic product (GDP), which is often used to measure the economic performance of a country. Gross output consists of products sold to final consumers (the GDP) as well as products sold to other industries where it is used as material or input. Today we will explore historical data on the gross output of the U.S. economy provided by the Bureau of Economic Analysis.
