This some Key slides from Population Unit You should have most of this already in your notes

Demography  the study of population patterns and change Population all the people of a particular area birth rate the number of births each year per 1,000 people Example: Birth rates are used to calculate population growth death rate the number of deaths each year per 1,000 people Death rates are used to calculate population growth. Subtract estimated death rate from Birth rate what do you get?

Population density the number of people in a defined area such as a square mile Demographers refer to this as calculating ‘population density population distribution the pattern, or spread, of people in a given area Demographers study not only the population density of a region but also population distribution.

Draw two conclusions about the population of the United States based on the map

Possible answers Some areas of the U.S. are much more densely populated than others. There are more people in the eastern U.S. than the western U.S. Coastal areas are heavily populated. There are areas of the U.S. where the population density is less than 1 person per square mile. The average population density of the U.S. is about 88 people per square mile.

What other factors may influence the distribution of people besides geographic factors. Discuss Major factors economic factors such as the availability or lack of jobs and political factors such as the stability or instability of governments.

Census the periodic count of a nation’s population by its government What things affect the birth rate or the death rate in a place? How have birth and death rates changed over time? Why do birth and death rates matter? natural increase” is the term demographers apply to the difference between birth and death rates. the birth rate minus the death rate “Calculating Natural Increase”

Calculating Natural Increase Directions: Calculate the natural increase per year, day and minute for each column below.   World More developed countries Less developed Countries Population, 2012 7,057,075,000 1,243,018,000 5,814,057,000 Births per Year 140,541,944 13,923,718 126,618,226 Day 385,046 38,147 346,899 Minute 267 26 241 Deaths per 56,238,002 12,191,662 44,046,340 154,077 33,402 120,675 107 23 84 Natural increase per 1. What conclusions can be drawn from the data?   2. What implications does this data have for the world?

Describe this map. why do you think the map is so distorted Describe this map. why do you think the map is so distorted. What is the purpose

a ‘cartogram.’ A type of map used to present statistical information's possible answers cartograms energy use, wealth, etc

Terms to Know More developed nations A country with a highly developed economy, including significant industry and technology. less developed nations fairly poor country with an agriculturally-based economy demographic transition theory/model describes the stages countries go through as birth and death rates change over time What is a theory????? Who's population is growing faster? Who has a larger population?

Should know stages of Demographic transition theory/model Source: http://www.geography.learnontheinternet.co.uk/topics/popn1.html Demographers have developed a theory or model that illustrates stages countries tend to go through as birth and death rates change over time due to a series of social and economic factors.
