The 1990, 2005 and 2020 population pyramid of the Philippines is typical of a developing country, broad on the base and tapering of at the top. The country’s high fertility and crude birth rates legacy is reflected in the 1990 and 2005 population pyramids, both characterized by a broad base that is largely made up of young population, ages 0-14.
In the next 15 years, not much change is seen as a cushion of the already high fertility rate and crude birth rate, the population is still expected to grow, the growth will be evident not only at the 0-14 age group but also to the economically productive age group, particularly in the prime working age group 20-49. Although, the economically productive age group will increase, there will still be more dependents than those who can provide. The increase in the number of young dependents (0-14 age group) by the year 2020 will require the government to invest more in the education and health sector of the country.
Japan The population pyramids of Japan for the years 1990, 2005 and 2020, reflects that which is somewhat the opposite of the Philippines’ population pyramid. The shape of Japan’s population pyramid is a “rocket-shaped” pyramid. It is wide at the middle, and narrow at the top and bottom. It can be observed that after 15 years, the 0-14 age group is now the ones comprising the 15-29 age groups. The 2005 population pyramid reflects a narrower base than that of the 1990 population pyramid. Thirty five years from 1990, the 0-14 cohort will now comprise the 35-44 age groups.
The population of Japan may be described as an aging population. The younger ones have entered the economically productive or working group, resulting to a more higher living standards and more better health conditions. This improvement in the health conditions, because they are working and earning well, they will have lesser children due to their careers and eventually this will lead to an increase in the old age population, as seen in 2020 population pyramid of the country. The increase in the old age population is also a reflection of a country’s improving health condition.
Thailand, like Mexico, is a country that has experienced a boom in the younger age group during the 1990s, as reflected in their population pyramid. But unlike the Philippines, Thailand’s age structure changed on the next 15 years. The 1990 broad base, indicating a population comprised by a large number of 0-14 age group, has in 2005 started to narrow down. The year 2020 reflects a more narrow base and an increasing number of the population in the economically productive age group. The changes in the age structure was attributed to Thailand’s strong population policy that aims to lower than fertility and crude birth rates.
Just like Mexico, should this change or trend continues, Thailand will experience great improvement in their economy, since more and more will be joining the economically productive age group and less will be the number of dependents.
