I notice there is a significant surplus of older adults, particularly in the female population, indicating a higher life expectancy for women compared to men. One reason could be the long-standing health disparities between genders, as women generally tend to have healthier lifestyles and lower rates of certain chronic diseases.
I also notice a contraction in the younger age groups, especially among males, suggesting a declining birth rate. It could be this way because economic factors, changing social norms, and shifting priorities among younger generations may lead to family planning decisions that favor smaller families or delayed parenthood.
