Since the Industrial Revolution, participation of women in the workforce outside the home has increased in industrialized nations, with particularly large growth seen in the 20th century. Largely seen as a boon for industrial society, women in the workforce contribute to a higher national economic output as measure in GDP as well as decreasing labor costs by increasing the labor supply in a society.

Women's lack of access to higher education had effectively excluded them from the practice of well-paid and high status occupations. Entry of women into the higher professions, like law and medicine, was delayed in most countries due to women being denied entry to universities and qualification for degrees. For example, Cambridge University only fully validated degrees for women late in 1947, and even then only after much opposition and acrimonious debate. Women were largely limited to low-paid and poor status occupations for most of the 19th and 20th centuries, or earned less pay than men for doing the same work. However, through the 20th century, the labor market shifted. Office work that does not require heavy labor expanded and women increasingly acquired the higher education that led to better-compensated, longer-term careers rather than lower-skilled, shorter-term jobs. Mothers are less likely to be employed unlike men and women without children.

The increasing rates of women contributing in the work force has led to a more equal disbursement of hours worked across the regions of the world. However, in western European countries the nature of women's employment participation remains markedly different from that of men.

According to the United Nations data, the female labor force participation rate for persons aged 15 and older was 53 percent in 2022. The highest was in the Oceania region (excluding Tuvalu) at approximately 65 percent, while the lowest was in Central and Southern Asia at 40 percent. Among individual countries, Iran had the lowest rate at 14 percent, whereas Nigeria had the highest at 77 percent—an increase of nearly 20 percentage points since 2019 (see the graphical representation: "Female Labor Force Participation for persons aged 15+ in select countries").

Worldwide, the proportion of women in senior and middle management positions has minimally increased between 2010 and 2020, staying around 34 percent on average. Developing countries, as well as emerging market economies, experienced a greater increase than developed countries (see the graphical representation: "Comparison of the Proportion of Women in Senior and Middle Management Positions by Region in 2010 vs. 2020").

Increasing women's equality in banking and the workplace might boost the global economy by up to $28 trillion by 2025.

Areas of study

As the Civil War raged in the U.S., Virginia Penny of Louisville, Kentucky, finished her research project and published the ground-breaking 1862 book, How women can make money married or single, in all branches of the arts and sciences, professions, trades, agricultural and mechanical pursuits.How women can make money married or single, in all branches of the arts and sciences, professions, trades, agricultural and mechanical pursuits (Philadelphia, 1862) Hoping to offer hard facts about what women in the workforce would encounter, Penny had interviewed thousands of employers, using both a survey via the postal mail and in person – when she would also interview workers. Many of her site visits were in Philadelphia, New York and Boston. She distilled her research to list over 500 jobs that were open to women as well as the information about the jobs and potential availability for women. She also indicated when employers offered their reasons for wage differentials based on gender.

She dedicated her book "to worthy and industrious women in the United States, striving to earn a livelihood", and the book garnered much attention from reviewers and scholars across the country. She sold her rights to the book to another publisher who put it out as an encyclopedia, The Employments of Women: A Cyclopaedia of Woman's Work,The Employments of Women: A Cyclopaedia of Woman's Work in 1863. It sold better once it was re-titled again in 1870 as How Women Can Make Money, Married or Single. In its several different versions, 36 editions were published between 1862 and 2006, and six editions of the adaptation in German (first published in 1867).

In the twentieth century, division of labor by gender has been studied most systematically in women's studies (especially women's history, which has frequently examined the history and biography of women's participation in particular fields) and gender studies more broadly. Occupational studies, such as the history of medicine or studies of professionalization, also examine questions of gender, and the roles of women in the history of particular fields. Women dominate as accountants, auditors, and psychologists.

In addition, modern civil rights law has frequently examined gender restrictions of access to a field of occupation; gender discrimination within a field; and gender harassment in particular workplaces. This body of law is called employment discrimination law, and gender and race discrimination are the largest sub-sections within the area. Laws specifically aimed at preventing discrimination against women have been passed in many countries; see, e.g., the Pregnancy Discrimination Act in the United States.

Women and economic development

Global research clearly delineates the correlation between women's role in the economy and an increase in the standard of living. In the 2001 World Bank report entitled "Engendering Development", the connection between women's involvement in the economy and growth is more clearly stated:While disparities in basic rights; in schooling, credit, and jobs; or in the ability to participate in public life take their most direct toll on women and girls, the full costs of gender inequality ultimately harm everyone…ignoring gender disparities comes at a great cost—to people's well-being and to countries' abilities to grow sustainably, to govern effectively, and thus reduce poverty.Society's intrinsic value is often associated with contribution and production as a whole, thus women's inability to participate in economy further solidifies a subordinate role in society. "The fact that women have fewer opportunities in labor market may contribute to their unequal treatment in the household…Increased opportunities for women in the labor market do indeed translate into better outcomes for women…For the same increase in total household income, an increase in female income of 7 U.S. dollars per month translates into a 1 percentage point increase in the survival rate for girls." Women are treated as less than men because their role in the home does not perpetuate survival of the family directly in terms of income. A stark realization of women's economic value in the eyes of under-developed countries is sex selective abortion rights and the alarming phenomenon of "missing women." What many societies fail to realize is that the trade-off to helping a woman instead of a man does not exist. When a woman is empowered with education and involvement in the economy everyone is better off. Women's economic involvement will drive up Gross Domestic Product (GDP) which is a foundational standard for higher living. James Wolfensohn of the World Bank states, "Education for girls has a catalytic effect on every dimension of development: lower child and maternal mortality rates; increased educational attainment by daughters and sons; higher productivity; and improved environmental management. Together, these can mean faster economic growth and, equally important, wider distribution of the fruits of growth… More education for girls will also enable more and more women to attain leadership positions at all levels of society: from health clinics in the villages to parliaments in the capitals. This, in turn, will change the way societies will deal with problems and raise the quality of global decision-making."

Paid employment globally

Women still contribute to their communities in many regions mainly through agricultural work. In Southern Asia, Western Asia, and Africa, only 20% of women work at paid non-agricultural jobs. Worldwide, women's rate of paid employment outside of agriculture grew to 41% by 2008.

One of the main forms of paid employment for women worldwide is actually a traditional one, that of the market "hawker". Women have worked outside the home as vendors at markets since ancient times in many parts of the world, such as Central America, South Asia, and Africa.

During the 20th century, the most significant global shift in women's paid employment came from the spread of global travel and the development of a large migrant workforce of women domestic workers seeking jobs outside of their native country. The Philippines is a major source of female domestic workers. Before the 1990s, the majority of Filipinos working outside the Philippines were male, but by 2012, an estimated 63% of Filipinos working overseas were female.

Estimates of Filipino women working overseas are in the millions. Over 138,000 new domestic workers gained permission to work overseas in 2012, a number that grew 12% from the previous year. Overseas employment often results in the women leaving their own children behind in the Philippines to be cared for by relatives. Domestic employees from the Philippines and other countries have also been subject to exploitation and sex and money extreme abuse, for example in several countries in the Middle East, where they are often employed. It is estimated that remittances from overseas workers (both male and female) bring $1 billion (USD) per month to the Philippines.

33% of the drivers and station controllers in the Bangalore metro are female in an effort to create a more welcoming and diverse workplace. Children of employees have access to childcare facilities, while women drivers can work at stations near to their homes and have access to a separate recreation area. If women are unable to perform night shifts, they work in the mornings or evenings.

Workforce participation by sector

Women and men often participate in economic sectors in sharply different proportions, a result of gender clustering in occupations. Reasons for this may include a traditional association of certain types of work with a particular gender. There is a wide range of other possible economic, social and cultural variables that impact the gender distribution in different occupations, including within a region or country. An averaging of statistics gathered by the United Nations for 2004 through 2007 reflects these differences (totals may not add up to 100% due to rounding):

More detailed statistics show large differences even within these regions. For example, 11% of employed women in East Asia are employed in agriculture, a number that rises to 55% in South Asia; 70% of women in Southern Africa are employed in the service sector, while in Eastern, Middle, and Western Africa this number is 26%.

According to the International Labour Organization, women's involvement in the labor force declines by 16.5% in developing nations as a result of unsafe public transportation.
