There are more old people then babies
For the entirety of Human History, the population of Earth has been skewed younger. Since the last population day on July 11th, they found there are now more people over 65 then there are under the age of 5. The World Population day was put into action by the United Nations Development Program in 1989 to find population issues and bring attention to it. They found by 2100 one in four people will be over 65, while only one in 20 will be under 5 years of age. The increasing longevity is successful for us, but also raises many pressing socioeconomic concerns. We will continue to age as a world, and the 2 age groups will continue to grow, but the over 65 population will double the number of children over 5 by 2050. Many developed countries had aged for a century, which gave them time to prepare for societal-wide changes. But on the other hand, many developing countries will become old before they become rich. The consequences of an older population are majorly economical. For example, supporting elderly people and their medical problems are much more expensive than caring for young people. Providing long term care, structured pension systems, as well as maintaining the labor force is expensive but mandatory for an older population. The aging trend is most prevalent in Japan, followed then by Europe and North America.
