POPULATION PYRAMIDS LESSON Objectives Intro to Population Name: ____________________________________ Period: ______ POPULATION PYRAMIDS LESSON Objectives 7A Construct and analyze population pyramids and use other data, graphics, and maps to describe the population characteristics of different societies and to predict future population trends. Intro to Population Pyramids Demography is the study of human populations and how they change over time. Demographers look at birth rates and death rates and human migration. These measures help them track population trends, or the general direction in which population numbers are moving. The diagrams above are called population pyramids. They show the makeup of a country’s population by sex and age groups. Geographers use such diagrams to study population trends in a country. The shape of a population pyramid shows how a country’s population is growing. A pyramid that is wide at the bottom shows rapid population growth. More babies are being born each year than the number of people who die. A pyramid with straight sides shows slow population growth, with births and deaths nearly equal in that country. A pyramid that is narrow at the bottom shows negative population growth. More people are dying each year than are being born.

We will use three classifications of development: Developed countries: wealthy, modern, urban, technological Newly industrialized countries: moving toward developed, industrializing and urbanizing Developing countries: poor, agricultural In the video and in a many other sources you will be exposed to, these countries are also described in terms of industrialization. Pre-industrializing, industrializing and post industrializing. What are the population trends occurring in each of the three stages of development? Developing Newly Industrialized Developed Pre-Industrializing Industrializing Post-Industrializing *Birth rate is high and death rates *Birth rates begin to fall due *Population remains stable or are starting to fall due to…. to… even begins to decrease because…. Real-Life Connections Population growth affects a country’s dependency ratio. This ratio compares the number of people too young or old to work with the country’s working age population. Both groups depend on other people to support them. A low dependency ratio means that workers have fewer dependents to support. A high dependency ratio means just the opposite—that there are a lot of young or old people for workers to support. 0-14 are considered young dependents 65-up are considered old-age dependents 15-64 are working age people who support these dependents. What might be policies to consider for each of the pyramids above? Democratic Republic of Congo United States Germany .

  • An Exploration of Human Population Demographic Data
    Tested Studies for Laboratory Teaching Proceedings of the Association for Biology Laboratory Education Vol. 32, 406–421, 2011 Behind the Numbers: An Exploration of Human Population Demographic Data Teresa C. Weglarz Department of Biological Sciences, University of Wisconsin – Fox Valley, 1478 Midway Rd, Menasha WI 54952 USA ([email protected]) Increasingly global population size has been a cause for alarm among scientists. Currently, global population size is 6.9 billion and estimates for 2050 range from 8-12 billion. It is estimated that the majority of population growth in the next 50 years will be in developing countries. This computer-based lab activity explores some of the social, economic, and political factors that influence population growth. Understanding the role of these factors in popula- tion growth is critical to the study of population demography. Population demographic data provides a glimpse into the population characteristics that are associated with rapid growth. The International Data Base provides popula- tion pyramids and demography data, on infant mortality rates, fertility rates, and life expectancy of populations in over 200 countries. This population demographic data provides a glimpse into the population characteristics that are associated with population growth and may provide clues on how to address population growth. Keywords: Population growth, demography, population pyramids Introduction Introduction Human demography is the study of population charac- tion data contains estimates and projections for more than teristics. The purpose of this computer investigation is to 200 countries, which includes population size, fertility, analyze the demographic relationships between different mortality and migration rates.

  • Pyramid Population Prediction Using Age Structure Model
    CAUCHY –Jurnal Matematika Murni dan Aplikasi Volume 6(2) (2020), Pages 66-76 p-ISSN: 2086-0382; e-ISSN: 2477-3344 Pyramid Population Prediction using Age Structure Model Heni Widayani1, Nuning Nuraini2, Anita Triska3 1,2,3Department of Mathematics, Faculty of Mathematics and Natural Sciences, Institut Teknologi Bandung Email: [email protected], [email protected], [email protected] ABSTRACT Population composition in a country by sex and age-structure often illustrated through the Population Pyramid. In this study, an age-structure model will be constructed to predict the population pyramid shape in the coming year. It is assumed that changes in population are affected by natality and mortality number in each age group, ignoring migration rates. The proposed age structure model formulated as a first-order partial differential equation with the non-negative initial condition. The boundary condition is given by the number of births which is proportional to the number of women at childbearing age. Then, this age structure model implemented utilizing United Nations Data to predict population pyramids of Indonesia, Brazil, Japan, the USA, and Russia. The population pyramid prediction of the five countries shows different characteristics, according to whether it is a developing or developed country. The results of this study indicate that the age structure model can be used to predict the composition of the population in a country in the next few years. Indonesia is predicted to be the highest populated country in 2066, compared to the other four countries. This result can be used as a reference for the government to plan policies and strategies according to age groups to control population explosion in the future.

  • Let's Put Demography Back Into Economics: Population Pyramids In
    Let’s Put Demography Back into Economics: Population Pyramids in Excel Humberto Barreto Q.G. Noblitt Professor of Economics and Management DePauw University Greencastle, IN 46135 May 11, 2016 Working Paper Please do not quote without permission. All comments welcome. Thanks to Frank Howland for early conversations and discussion, especially on Cuba, and Andrew Pinney for help on understanding estimates of Afghanistan’s population. Abstract In 1960, George Stigler wrote that, “In 1830, no general work in economics would omit a discussion of population, and in 1930, hardly any general work said anything about population.” Today, the economics curriculum remains largely devoid of demography and this needs to change immediately. After witnessing a population explosion in the last half of the 20th century, fertility rates are crashing throughout the world. We are in the midst of another demographic sea change, slamming on the brakes right after accelerating faster than ever before. This has important consequences for economies everywhere. Instead of glibly tossing a dependency ratio onto a slide, this paper offers an easy way to improve demographic literacy in undergraduate economics students using population pyramids. Hypothetical data are used to explain the pyramid and teach its dynamic properties, then real-world data are used to provide historical context, current demographic snapshots, and a glimpse of the future. Throughout, Microsoft Excel is used and its ability to download data directly from the US Census Bureau’s International Data Base with a single click of a button provides a flexible, powerful tool to explore various countries. Download PopulationPyramid.xlsm from academic.depauw.edu/~hbarreto/working and follow along with the instructions provided in this paper.

The world population reached 7,40,00,000 on 6th February, 2017. Alarmed by the figure of global population which registered five billion on the 11th of July 1987,1 the celebration of the World Population Day was started in the year 1989 by the Governing Council of the United Nations Development Programme (UNDP). It is an international event celebrated every year on the 11th of July all over the world to create awareness of the exploding population and its ill effect. The objective of this article is to appraise the readers about the adverse impact of overpopulation and significance of celebrating the World Population Day. [1] - Source-Population pyramid.net The world population reached 7,40,00,000 on 6th February, 20171. As per the World’s Population clock2, the population touched an alarming figure of 7,50,15,11,766 at 16.21 hrs on the 24th April 2017. By 2025, it may exceed 8 billion. Around 2040 it could touch a figure of 9 billion and by 2100 our planet could be home to a massive 11 billion persons which could be beyond the capacity of this planet to sustain.
