What's inside is more than just rows and columns. Make it easy for others to get started by describing how you acquired the data and what time period it represents, too. This dataset contains over 48,000 rows of data based on US census data. This dataset is used to determine whether an adult's income exceeds $50K/yr based on 14 different attributes collected. The dataset contains a distribution of 23.93% entries labelled with >50k and 76.07% entries labeled with < with <=50k. The attributes are as follows:

The median age in the United States reached 39.2 years in 2024. This was up from 28.1 in 1970, reflecting a significant aging of the population. Over the coming decades, the number of retirees is projected to rise by about 40 percent by 2050. This demographic shift will present new challenges to American society, reshaping patterns of consumption, work and public policy in the decades ahead. Can an older America balance the books? Social Security spending is set to rise as America grows older. The program, which is the government’s main pillar of support for retirees, already absorbs about five percent of GDP. This could reach six percent by 2035. That trajectory will keep pressure on policymakers to balance promises to pensioners with broader fiscal constraints. A world growing older The aging trend is not unique to the U.S. The global median age reached 30.9 in 2025, up from 20.3 in 1970. By 2050, China, Japan and South Korea are expected to rank among the countries with the largest shares of people aged 65 and over. The change will oblige policymakers to adapt long-standing arrangements to societies where a larger share of people are in later life.

The 1995 Survey of Adults on Probation (SAP) was the first national survey to gather information on the individual characteristics of adult probationers. The SAP was a two-part nationally representative survey consisting of a records check based on probation office administrative records and personal interviews with probationers. The records check provided detailed information for 5,867 probationers on current offenses and sentences, criminal histories, levels of supervision and contacts, disciplinary hearings and outcomes, and demographic characteristics. Only adults with a formal sentence to probation who were not considered absconders were included in the records check. Excluded were persons supervised by a federal probation agency, those only on parole, persons on presentence or pretrial diversion, juveniles, and absconders. The records check forms were completed by a probation officer or by another person knowledgeable about probation office records. A subset of the population selected for the records check was selected for a personal interview, resulting in a total of 2,030 completed interviews. The personal interview sample excluded from the records check sample probationers not on active probation (defined as being required to make office visits at any interval), those incarcerated, and those in residential treatment. Respondents were asked about current offense(s) and supervision, criminal history, alcohol and drug use and treatment, mental health treatment, demographic characteristics, and a variety of socioeconomic characteristics such as employment, income, receipt of welfare, housing, number of children and child support, and living conditions while growing up.

In terms of population size, the sex ratio in the United States favors females, although the gender gap is remaining stable. In 2010, there were around 5.17 million more women, with the difference projected to decrease to around 3 million by 2027.

Gender ratios by U.S. state In the United States, the resident population was estimated to be around 331.89 million in 2021. The gender distribution of the nation has remained steady for several years, with women accounting for approximately 51.1 percent of the population since 2013. Females outnumbered males in the majority of states across the country in 2020, and there were eleven states where the gender ratio favored men.

Metro areas by population National differences between male and female populations can also be analyzed by metropolitan areas. In general, a metropolitan area is a region with a main city at its center and adjacent communities that are all connected by social and economic factors. The largest metro areas in the U.S. are New York, Los Angeles, and Chicago. In 2019, there were more women than men in all three of those areas, but Jackson, Missouri was the metro area with the highest share of female population.
