There death and Birth Rate is higher because they are poor, so they dont have medicine for vaccines and food. Usually, as they lose a child, they have another one. And the richer have lower because they have the money to blow on medicine and are too selfcentered for children, most of the time.
They need to have more births because poorer countries tend to have a higher child mortality rate, so they need to keep giving birth until 1 or 2 survvies
By having more kids. In poor countries mostly, they have a high birth rate because they arn't educated about it. In richer countries like the USA, some women might want to start a career and not have children until they are 30.
For lots of reasons. They may not have enough food. Diseases are more widespread. They don't have as good a health service as richer countries. Living conditions are not good, so they may not have clean water and the standards of hygiene are not as good. Many poor countries experience famine. Many poor countries are not as well equipped to deal with natural disasters, so they suffer more when they happen. For all of these reasons and many others, the death rate is higher and life expectancy is lower in poor countries than in richer countries.
Demographic transition
No, it is actually the opposite. A high birth rate and a low death rate leads to increased populations.
That birth rates vary from country to country, is a relatively new phenomenon. The reason why there are different birth rates is that the countries are in a different state of the so called 'demographic transition'. It usually has 4 stages which a country passes: Stage 1: High birth and high death rate (all countries before industrial revolution) Stage 2: High birth and falling death rate (some African countries) Stage 3: falling birth rate and low death rate (most of the developing countries) Stage 4: low birth rate and low death rate (developed countries) The birth rates fall because there's no need for children as workers anymore. Countries in stage 1 and 2 are rural societies that demand child labor in the fields. The people have also to compensate the high infant mortality rate. In stage 3 lesser and lesser people work in agriculture and children are no longer an economic benefit but a burden for the parents. There's also much divergence in the birth rate in stage 4 countries. Most of the developed countries will go to the Stage 5 of the transition, with a death rate higher than the birth rate. Only two developed countries will not: USA and Israel. This has cultural reasons.
Developing countries have high rates of natural increase as their birth rates are high, and although their death rates are also high there is usually a big gap between the two figures. Malawi's natural increase is 30 per year for every 1,000 people. This is calculated from the Birth Rate of 51 minus the Death Rate of 21 (51 - 21=30). Developed countries have both a low death rate and low birth rate, with only a small gap between the two. Norway's natural increase is 3 per year for every 1,000 (14 - 10=3).

Demographic transition
a high death rate and a high birthrate.
in many LEDCs (less economically developed countries) this is the case. this is due to high infant mortality (death a birth) caused by poor health care. so many families have a number of babies as there is a high chance they will die
