Key Issue 2: Where has the world’s population increased?
Thorouoghly Explain using bullet points for summary and illustrations CRUDE BIRTH RATE, CRUDE DEATH RATE, TOTAL FERTILITY RATE (PG. 53-54) NATURAL INCREASE RATE, DOUBLING TIME (PG. 53-54) PRO-NATALIST, ANTI-NATALIST (INTERNET RESEARCH) INFANT MORTALITY RATE, LIFE EXPECTANCY PG. (55-57) DEMOGRAPHIC TRANSITION MODEL BRIEF DEFINITION AND STAGE 1, AGRICULTURAL REV (PG. 57-58) Demographic transition model Stage 2, industrial rev, medical rev (pg. 58-59) Demographic transition model Stage 3 & stage 4, zero population growth (pg. 59) Demographic equation, demographic momentum (internet research) population pyramid, Dependency ratio, sex ratio (pg. 61-62)
Crude means: looking at society as a whole!
Total number of live births in a year for every 1,000 people
Total number of deaths in a year for every 1,000 people
Natural Increase Rate: subtract CDR from CBR (CBR – CDR) after converting to a %
Doubling Times The doubling time is the number of years before a population will be twice as large as it is today. World = 50 U.S. = 34 MDC = 543 LDC = 40 Honduras = 22 Belize = 19 Denmark = 700 Japan = never?

High infant mortality tends to result in higher fertility rates as families seek “insurance” for the loss of children.
