Today's population is younger that ever before. Select all responses that explain why.?

Today's population is younger than ever before primarily due to advancements in healthcare and technology, which have increased life expectancy and reduced infant mortality rates. Additionally, high birth rates in certain regions, especially in developing countries, contribute to a younger demographic. Furthermore, migration patterns often show younger individuals moving to urban areas for better opportunities, which can skew the age distribution in those regions. Lastly, access to education and family planning resources influences reproductive choices, shaping the age structure of the population.
