Population pyramids: Powerful predictors of the future

"Population statistics are like crystal balls -- when examined closely, they can help predict a country's future (and give important clues about the past). Kim Preshoff explains how using a visual tool called a population pyramid helps policymakers and social scientists make sense of the statistics, using three different countries' pyramids as examples."

Unit 2: Population and Migration

 

This video was about how demographers categorize data and analyze it. This video showed a few different population pyramids in order to show differences in population in different countries. It showed China as an example and pointed out the remnants of the one child policy 35 years before and how the number of men were higher due to sex selective abortions. They also talked about how the population pyramids could show what stage in the demographic transition model a country was in and how they use them to predict future patterns and changes. 

 

This relates to unit 2 because it covers topics such as population change, demographic transition models, sex composition, population policies and much more. Population pyramids are very useful due to the visualization of sex, age and number composition in a countries population. They are very important in the use of predicting the future change in population because it can tell what the population has gone through in the past and what to expect in the DTM. 

Daniel Lindahl's curator insight, March 21, 2015 10:43 PM

This video illustrates how population pyramids have the ability to show how populations will rise and fall over time. Pyramids specifically show the population based on a specific age, and illustrates a country's amount of young people in comparison to the elderly.

As U.S. birth rate drops, concern for the future mounts

As U.S. birth rate drops, concern for the future mounts | Geography in IB @BIS | Scoop.it

"The nation's fertility rate has slipped below replacement levels partly because of the recession and a decline in immigration. That's raising concern about the nation's future."

These stats are hard to take in, because it seems like even though birth rates are considered to be dropping, the country’s total population continues to rise, and fast. Immigration probably plays a major role in the adding of new citizens, though just because birth rates are decreasing it shouldn’t necessarily mean a bad thing. With a slow increase of people, there could possibly be drops in the unemployment rate, or even poverty level at a big stretch. With fewer people in the country, it could mean less competition among others, leaving more options for people to pursue. It says at the end of the article that, “there are no cases of peace and prosperity in the face of declining populations.” This may hold true to an extent, but look at China for example. Their population is the largest in the world, containing roughly 20 of the 30 most polluted cities and being the top consumer of energy. Though the country has an unemployment level which is half of ours, they must put in place family planning methods such as the “one-child policy” to hope for better population control. If I know the United States, I highly doubt they would ever resort to such measures, unless the government wants uproars. So maybe I’m optimistic about the birth rate drops, but it shouldn’t be too much of a problem. Maybe we should rid of the self-checkouts and automated answering machines and slowdown in technology so we don’t find ourselves in a situation that’d become too hard to handle.

This decline in birth rates is largely due to the recession; people don’t want to have children because they can’t afford the care. We need to have a balance in our population. Having one age group, like elderly people, dominating over other generations can be a problem. Even though the birth rates are decreasing, our population is still growing at a steady rate. Immigrants trying to make a home for themselves and their families in the United States contribute in a big way to our population increase.
I think that when and if the economy bounces back, families will start to feel comfortable with their finances and the birth rate will spike. Yet, if the birth rate does get back to normalcy and the immigrants continue to come to this country maybe our population will see too much of an increase and overpopulation could be a problem. But I doubt our country will ever adopt the “one-child policy” currently in use in China, we will find some other way to control our population, whatever that may be.

The recession is a huge factor as to why the birth/fertility rate is dropping. It costs a lot of money to have a child and most people can’t afford to care for themselves never mind another baby. Even though the birth rate has been decreasing over the years, the population is still increasing due to immigration. With the birth rate decreasing the level of poverty could potentially decrease as well because there will not be an economic burden. I don’t think there should be too much of a concern about the birthrate dropping because once the economy returns to normal I’m sure people will want to expand their family. I do agree to a certain extent with the statement in the article: “Population growth leads to human innovation, and innovation leads to conservation ... There are no cases of peace and prosperity in the face of declining populations.” Overpopulation, like in China, causes many issues, not just economically.

Gender imbalances in China have created a generation of men for whom finding love is no easy task

Elizabeth Bitgood's curator insight, April 10, 2014 11:19 AM

Because of china’s one child policy the pool of available women had gone down, this leads many rural women to wish to marry up in economic circumstances leaving many rural men unmarried and once they pass the age of 30 less likely to ever marry.  China’s quandary with unbalanced sexes is a graphic example of what happens when one gender is preferred above anther leading to a reversal within a generation when scarcity of the other sex sets in.  Hopefully this experience will teach China to value both men and women in the future.

Kaitlin Young's curator insight, November 20, 2014 9:22 AM

The one child policy coupled with a traditionally patriarchal society has created a major problem in China in regards to men finding a wife. The preference towards having a baby boy over having a baby girl has led to abortions and infanticide in order to secure a male child. Unfortunately, this has resulted in a severely larger male population. In China's growing economically aware society, women have all the power to ultimately chose their spouse, often times considering wealth and status over any other characteristics. In a way, the power and fate of China has shifted to the women of marrying age while millions of poorer, working class men are left to live their lives unmarried and alone.  

 

Hector Alonzo's curator insight, December 15, 2014 8:42 PM

The more well off Chinese males are more apt to get with woman. Due to the gender imbalance caused by the one child policy of China, it is harder for the men who are born into less fortunate families to get married and that will cause them to lose out on love.
