A new study out shows that for the first time in history, women with one or more college degrees are more likely to be married by age 40 than their lesser-educated counterparts. The study, conducted by a sociology professor at New York University, followed women born between 1958 and 1964 and found that the more educated women marry later in life, however, more of them marry at some point compared to the less educated women. This study reflects a change in expectations of women and their husbands, with many husbands no longer expecting their wives to stay at home.

Demography is the statistical study of human populations. It includes the study of the size, structure, and distributions of different populations and changes in them in response to birth, migration, aging, and death. It also includes the analysis of the relationships between economic, social, cultural, and biological process influencing a population. The field of sociology draws on huge bodies of data generated by a variety of sources, including the U.S. Census Bureau. Read more about demography and how it is used in social science studies.

A new study published in the Journal of Black Studies shows that restaurant wait staff regularly discriminate against African-American diners. More than 200 servers in 18 North Carolina restaurants were surveyed and 38% of the respondents admitted to giving African-American customers poorer service based on the expectation that black diners would be poor tippers, demanding, and rude. The black diners that were surveyed reported that they were mistaken for valet parkers, coat checks and bathroom attendants in addition to receiving poor service while dining. This "tableside racism" is yet another example in which African Americans are stereotypes and treated poorly in everyday situation. Read more about the study and findings.

In statistics and research, you will often hear the term normal distribution, but what exactly does this mean? A normal distribution is a theoretical idea that is based on theory rather than real data. Normal distributions are typically the goal and the ideal in research and data and something that every researcher strives for. A normal distribution is a distribution that is bell-shaped and symmetrical. The mean, median, and mode are all the same and coincide with the peak of the curve. The frequencies then gradually decrease at both ends of the curve. The normal distribution is also often called the bell-shaped curve because of its shape. Read more about the normal distribution and see a picture that illustrates what a normal distribution looks like.
