The document discusses population structure and its representation through population pyramids. It defines key terms like CBR, CDR, and life expectancy. Countries are expected to be at different stages of the demographic transition model based on their CBR and CDR. Population pyramids show the ratio of age groups in a population and how this structure impacts a population's needs. Interpreting pyramids involves placing descriptive sentences on sample pyramids from France and Kenya. Calculating a country's dependency ratio involves dividing the number of non-working young and elderly by the working-age population. Homework involves calculating dependency ratios for several countries.

Joel Serra Bevin

Diversity is an inherent characteristic of global cities and is likely to intensify in the future as globalization spurs complex migration flows. Spatial segregation, as measured by the dissimilarity index, is calculated and analysed in three global cities: Barcelona, London and Melbourne. Understanding its formation and representation is crucial in order to achieve both migrant integration and host society acceptance.

Demographic Transition 1- Construct a graph of birth and death rates i.docx

theresar3

Demographic Transition 1. Construct a graph of birth and death rates in Mexico (you may use the blank graph provided below if you would like). Be sure to include vertical lines for the demographic transitions and label the corresponding stages. Remember, not all 4 stages are necessarily present! Values are given as annual rate per 1000 people. Include all elements of a proper graph - title, axis labels, linear axis spacing, a key if using more than one line. 2. The stage of demographic transition that a country is experiencing is often used to help determine its status as pre-modern, industrializing, industrial, or post-industrial. Referring to your graph above, what stage do you think Mexico would be categorized as? Why? Population Dynamics A world population pyramid (also called an age-class histogram) can be created when the population statistics from both the developed and developing nations of the world are combined (see below). 3. Based on the shape of the world population pyramid, do you think the world population is growing slowly, rapidly, or not at all? Explain your answer. 4. Using the data in the table above (note - the percentages represent percentage of gender so the female column will total 100% and the male column will total 100% ), what is the total percentage of females in pre-reproductive years ( 0 14 ) and males in pre-reproductive years ( 0 14 ) ? What is the total percentage of females and males between the ages of 20 and 29 ? The age pyramids below represent the populations of three nations: one growing rapidly (Kenya), one growing slowly (US) and one that is not growing at all (Italy). 5. Which population includes the greatest percentage of people over the age of 65 ? What percentage of that nation's population falls into that category (approximately)? 6. Which nation has the greatest percentage of people in pre-reproductive years (ages 0-14)? What percentage of that nation's population falls into that category (approximately)? 7. Which nation has the greatest percentage of people in child-bearing years (ages 15-44)? What percentage of that nation's population falls into that category (approximately)? 8. What has to change to change the shape of a country's age pyramid in the future? 9. Which country is most likely experiencing old-age dependency ratio issues? Youth dependency ratio issues? .

Basic Income, Alternate Outcomes

John F.C. Cheong

Basic income research proposal responding to Y-Combinator's first "Request for Research" issued on January 27, 2016. Outlines a research program targeting the "millennial hamster tribe" whose members fit a certain Reiss Profile.The research design is organized around a mission-specific community currency administered via "smart contracts" on the Ethereum platform (everything hands-off automated!), and uses a multi-armed bandit algorithm to optimize the use of real money resources (so the program won't run out of money before it's time!). Includes an overview of "how everything fits together" overlaid on top of a slightly modified business model canvas.

MDC and LDC Populations WorksheetDemography is the statistical s

AbramMartino96

MDC and LDC Populations Worksheet Demography is the statistical study of human populations, especially with reference to size, density, distribution, and vital statistics (relating to births, deaths, marriages, health and disease, etc). In making population projections for different countries, demographers look at the profile of the countries’ residents. They ask: What are the ages of the people? How many are men? How many are women? Using this information, they construct “population pyramids” (a.k.a. age histograms) like the ones the class will use in this activity. These graphs illustrate the configuration of a country’s population as shaped by 70 to 80 years of economic, political and natural events. Procedure: You will find information about the populations of two countries; the United States and one other country picked from a list on the last page. Countries Assigned = USA and ____________________________ Log onto the web and go to International Data Base (IDB) part of the www.census.gov site (The URL is https://www.census.gov/data-tools/demo/idb/#/table?YR_ANIM=2021) 1. For the report tab, select “Custom Report”. 2. In custom report columns tab select all data in the tables below. 3. In the select by County/Area tab, select the Country. 4. Use the data for this year to answer the questions on this page below. 5. In the resulting webpage, click on your Country’s name to access the population pyramid graph. 6. Right click on the graph so you can copy it and then past it at the end of this worksheet. 7. Repeat for your second country. Using the information from the internet for this year, fill out the tables for both of your countries UNITED STATES fill in country name What is the Crude Birth Rate? What is the Crude Death Rate? What is the life expectancy at birth? What is the infant mortality rate? What is the Total Fertility Rate (FTR)? What is the growth rate today? What is the doubling time for the population? (You will have to work this out so look at the population lecture!) Show your math work! Still on the International Data Base (IDB) site (The URL is https://www.census.gov/data-tools/demo/idb/#/table?YR_ANIM=2021) 1. To obtain the population by age group, scroll/mouse over the population pyramid. The population totals for each 5-year group will appear. 2. Add up the numbers in each group to comprise the three categories below. Once you have the population size of each category you can calculate the % of the population made up by that age group using the following calculation: 3. (Population size for the age group ÷ total population size) X 100 = % of population 4. Calculate this information and add the results to complete the table below. Repeat your for second country UNITED STATES fill in country name Age Group Population size for both Sexes % of population Population size for both Sexes % of population 0-14 Pre-Reproductive Pre-Reproductive 15-44 Re ...

Gen Y - Changing the Rules of the Game?

Accord

Gen Y, the latest entrant in the multi-generational workforce, is a unique group. They are young, ambitious and dynamic; but their value systems at work are quite different from the other generations. This new breed of socially connected professionals with multiple interests can (and probably will!) bring about a radical change in the work cultures of companies. The big challenge facing organisations is not only building better working relations between the different generations, but also engaging Gen Y effectively to bring about a new and positive work culture that benefits everyone. This presentation looks at the Gen Y workforce in Singapore and gives a few insights on which areas companies should be looking at for effective engagement with Gen Y.
