Stage 1: *Low growth
High but fluctuating CDR and CBR. Low NIR. Population composition is youth dependency
Stage 2: *high growth
CBR remains high. CDR plummets due to improved nutrient, sanitation, and medication. NIR rapidly grows. Population composition on youth.
*MDS enters industrial revolution and 150 yrs later LDCs enter Medical revolution
Stage 3: *moderate growth
CBR falling, CDR falling slowly, NIR increase slows, population composition, mostly youth-people surviving longer
Stage 4: * low growth
CBR low, CDR low, NIR falls and stays at low growth, population composition, shifts to elderly
*women education-less babies
