However, the area surrounding CF10 1SZ, has a female population slightly higher than UK average, with 53.6% of residents being female. Several factors can contribute to this.

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.
