What stage of DTM has low population growth (slow) but sees fluctuation due to uncontrollable disease, famine, war-- sometimes referred to as HIGH stationary?

Stage ONE DTM NIR/RNI

What stage of DTM has High growth- Population Explosion?

Stage TWO DTM NIR/RNI

What stage of DTM has Moderate population growth, but growth rate is slowing?

Stage Three DTM NIR/RNI

What stage of DTM has low growth (low stationary ) due to near equally low birth and death rates often reaching zero population growth ZPG?

Stage four DTM NIR/RNI

What stage of DTM has Negative growth aka population decrease (contraction) as birth rate drop below death rates?

Stage five of DTM NIR/RNI
