Questions1. What type of growth is

reflected in the graph? Rapid, Slow, or Negative

2. What level of development is reflected in the graph? More, Newly Industrialized, or Less

Why are the largest percentage of people between the ages 50-54?

What has curtailed the population growth in this country?

Demographic Transition Model

Stage 2: Industrializing - High Birth/Rapidly Decreasing DeathNewly Industrializing - Transition from Primary to Secondary Economic Activities

Stage 1: Pre-Industrial -High Birth/High Death

Less Developed - Primary Economic Activities

Stage 4: Post-Industrial - Low Birth/Low Death

More Developed- Mostly Tertiary Economic Activities, emergence of Quaternary Economic Activities

Stage 3: Industrialize - Rapidly Decreasing Birth/Low Death- Newly Industrializing Mostly Secondary Economic Activities, Emergence of Tertiary Economic Activities

mapping variable is substituted for land area or distance.
