In the
beginning of human geo class, we spent about twenty minutes completing or tests,
because that was about how long the fire drill lasted on Friday. Once everyone
had finished, we began a new unit on population and migration. The class took
notes on a power point we viewed. We only got about halfway through the power
point and it covered terms like life expectancy, crude birth rate (CBR), crude
death rate (CDR), and rate of natural increase (RNI).
Life expectancy- The average number of years to be
lived by a group of people born in the same year.
Crude birth rate (CBR) - Number of births per 1000 of
the population
Crude death rate (CDR) – Number of deaths per 1000 of
the population.
Rate of natural increase (RNI) – Subtract the death
rate from the birth rate and divide by ten.
Our class
will complete the power point the next time we meet which will be tomorrow.
