What We Did in Class Today October 8, 2010 (My Birthday!!!)

TODAY WAS MY BIRTHDAY!!!!!!!!!! Today in class, we talked about the crude birth and death rate of different countries. We talked about how this effects us, and how it will affect us in the future. We also talked about the total ferterlity rate of different countries, and how the rate of some countries will affect us when we get older. Mr. Schick said that when we get older, we might have a water shortage, and water will be very expensive. Also we might have a shortage on food, and other things that humans need to survive. I took lots of notes on everything that we talked about in class today.

Here are all of my notes:

90% of the world's population growth takes place in the development of countries

14,000 births per hour

Increasing by over 80 million per year

By 220,980 per day (in 2009)

Over 6.8 billion people on the planet right now

In about 12 or 13 years, there will be another billion people on the planet

We have enough food in the world, to feed everyone in the world, but the problem is getting it to them

As the population of the world increases, we might have a shortage of water, food, and other things that people need to live

High: Japan: 82.6 total……. 79.0 men…… 86.1 women …..  Life expectancy

United Stated… ranked #38… 78.2 total……. 75.6 men……. 80.8women…..Life expectancy

Low: Swaziland:…..31.9 total…. 31.6 men……… 32.2 women…..Life expectancy

Rate of natural increase: subtracting the death rate from the birth rate, then divide by 10

This gives us the annual natural growth rate - in percentage form - for a country or region

Crude death rate: number of deaths per 1000 of the population

Crude birth rate: number of births per 1000 of the population

Net migration rate: the difference between the number of people entering and leaving a country during a year

An excess of people entering the country is net immigration

Written as a positive number

An excess of people leaving a country is net emigration

Written as a negative number

Push forces:   civil war, environment degradation, unemployment, religious or ethnic persecution

Pull forces:     better economic opportunity, better health services, religious freedom, political freedom

TFR: average number of children born per woman

For a population to remain the same, the TFR must be 2.1

Higher than 2.1: population raises

Lower than 2.1: population falls

World TFR: 2.54

US TFR: 2.05

Europe's TFR: 1.45

Africa's TFR: 5.14
