In the UK, the overall gender distribution is approximately 49% male and 51% female. However, the area surrounding CF15 8AH, has a female population slightly higher than UK average, with 53.5% of residents being female. Several factors can contribute to this. Women generally live longer than men, resulting in a higher proportion of women in neighborhoods with significant elderly populations. Typically, as people grow older, they tend to relocate from city center addresses to suburban areas, smaller towns, and rural locations. Consequently, these areas often have a higher number of females. A higher female population can also be found in areas with industries that employ more women, such as healthcare, education, and retail.
