Demography is the study of populations. In the context of urbanization, it looks at how population patterns (such as age and gender) connect to social, political, and economic relationships in cities.

Age

Aging and the life course

• In the U.S., socialization is strongly shaped by age norms across the life span. As people age, they move through expected transitions into new roles, such as starting school, entering the workforce, or retiring.

Age cohorts and social significance of aging

• An age cohort is a group of people born during the same time period. Looking at a population’s age distribution helps reveal social and cultural trends and supports planning for future social and economic needs.
  • Baby Boomers - those born between 1946 and 1964 - are now in their 60s and 70s. This generation came of age during the 1960s and early 1970s and generally experienced higher earnings and a higher standard of living than previous generations. However, many did not adequately prepare for retirement. The reasons for this vary, including high spending, economic downturns, and company closures that reduced pension payments. Many also faced the rising cost of higher education while helping pay for their children’s college. Regardless of the cause, many retirees report concerns about financial insecurity and the possibility of outliving their savings.

There is also growing concern about the sustainability of Medicare and Social Security. In principle, when enough workers contribute to Social Security, retirees can withdraw benefits as needed. However, as more Baby Boomers begin to claim Social Security while fewer younger workers contribute, there is a risk that the Social Security trust fund could be depleted within the next decade.

The challenges of an aging population are not unique to the United States. By 2050, the global population of people aged 65 and older is estimated to reach 1.5 billion.

• Generation X - individuals born between 1965 and 1980, often recognized for self-reliance, strong dedication to work, and an emphasis on maintaining a healthy work-life balance. They tend to be practical and skeptical of traditional institutions, prioritizing job stability and financial security. They are also adaptable to technology but often prefer a more independent, less intrusive management approach. In the U.S., members of Generation X may need to retire very late in life, or not at all, because the proposed retirement age for their generation is seventy. Many are already caring for aging parents and even grandparents, while also raising children or beginning to welcome grandchildren.

• Millennials, born between the early 1980s and the mid-1990s, often view the transition from childhood to adulthood - and aging itself - differently than Baby Boomers. This generation was strongly affected by the 2008 financial recession, which occurred as many were entering, attending, or graduating from high school and college. With job opportunities at historic lows, many graduates struggled to find work. Some moved back in with their parents and faced difficulties repaying student loans. These delays in achieving economic independence have also postponed the ages at which many Millennials marry or partner, buy homes, and have children.

• Generation Z refers to individuals born between 1996 and 2010. This generation is the most racially and ethnically diverse to date and is on track to have the highest average level of education. Gen Z is often recognized for idealism, a strong commitment to inclusivity, and advocacy for social progress. As “digital natives,” they were born into widespread technology use and have little to no memory of life before smartphones. They were also particularly affected by Covid-19, whether as students or as young employees - often in jobs disrupted by the pandemic, such as serving and retail.

Age stratification theory suggests that society categorizes individuals based on age, similar to how it differentiates people by race, class, and gender.

Gender

Gender refers to the social and cultural distinctions associated with behaviors traditionally categorized as male or female.

Sexual orientation

• Sexual orientation refers to an individual’s enduring emotional, romantic, and/or sexual attraction to people of the same gender, a different gender, or multiple genders. It exists on a spectrum and is distinct from gender identity.
• Common orientations include heterosexuality (attraction to the opposite gender), homosexuality (attraction to the same gender), and bisexuality (attraction to both genders). Some people identify as asexual, experiencing little to no sexual attraction, while others use terms like pansexual to describe attraction regardless of gender or transgender status.
• Sexual orientation is shaped by a complex interplay of biological, psychological, and social factors. It is widely recognized as an intrinsic aspect of identity rather than a choice. Societal attitudes toward different orientations vary across cultures and historical periods, influencing acceptance, legal rights, and social inclusion.

The social construction of gender

• Gender characteristics can vary widely across societies because gender is socially constructed. Hair length, for example, has been associated with masculinity or femininity differently across cultures and time periods.
• The binary view of gender - categorizing people strictly as either male or female - is not universal and is specific to certain cultures. Some societies understand gender as more fluid.
• Gender roles are societal expectations for how men and women should present themselves and behave. These roles are shaped by cultural norms and standards. Children learn gender roles through play and by imitating behaviors they observe around them.

Gender segregation

• Gender segregation is the practice of dividing activities, services, or environments by “gender.” Examples include separate male- and female-labeled restrooms, separate divisions in sports, or designated rooms in a gym for females. Commonly cited reasons include comfort, safety, or fairness in competition, though research and public opinion actively debate these factors and examine unintended consequences, such as the exclusion of transgender individuals.
• In some communities, gender segregation is widespread for religious or cultural reasons. For example, Orthodox Jews and more conservative Muslim individuals or communities may separate men and women outside the home by sitting in separate sections in places of worship, keeping distance on the street, and sometimes offering separate seating on public transportation.
