Baby tree in the third world, while fertility rates fall in richer countries

Rising birth rates in developing countries create a worldwide baby boom, while women in dozens of richer countries do not produce enough children to maintain the population level there, figures released on Friday.

A global overview of birth, mortality and sickness percentages when evaluating thousands of datasets per country also showed that heart disease was the only cause of death worldwide.

The Institute for Health Metrics and Evaluation (IHME), set up by the Bill and Melinda Gates Foundation at the University of Washington, used more than 8,000 data sources – more than 600 of them new – to create one of the most detailed considerations worldwide to establish Public Health.

Their sources include research in the country, social media and open source material.

In Africa and Asia fertility rates continue to grow while Europe and North and South America do not produce enough children to maintain their current population. PICTURED: the total total fertility rate divided over the number of live births per region for both sexes from 1950 to 2017

It turned out that while the world's population rose from 2.6 billion in 1950 to 7.6 billion last year, that growth was highly uneven to region and income.

Ninety-one nations, mainly in Europe and North and South America, did not produce enough children according to the IHME study to maintain their current population.

But fertility rates continued to grow in Africa and Asia, with the average female in Niger having seven children during her lifetime.

Ali Mokdad, Professor of Health Metrics Sciences at IHME, told AFP that the most important factor in determining population growth is education.

It has to do with socioeconomic factors, but it is a function of a woman's upbringing, "he said. & # 39; The more a woman is raised, she spends more years at school, she delays her pregnancies and so they will have fewer babies. & # 39;

The IHME discovered that Cyprus was the least fertile nation on earth, with an average woman who only gave birth once in her life.

By contrast, women in Mali, Chad and Afghanistan have on average more than six babies.

& # 39; Less mortality, more disability & # 39;

The United Nations predicts that by the middle of the century more than 10 billion people will be on the planet, generally in accordance with the IHME projection.

This raises the question of how many people can support our world, known as the & # 39; carrying capacity & # 39; from the earth.

Mokdad said that while the population continues to rise in developing countries, their economies generally grow.

This usually has a domino effect on fertility over time.

"In Asia and Africa the population is still increasing and people are moving from poverty to a better income – unless there are wars or unrest," he said.

& # 39; Countries are expected to perform better economically and it is more likely that fertility will decrease there and will level off. & # 39;

Not only are there billions more of us than 70 years ago, but we also live longer than ever before.

The study, published in the medical journal The Lancet, showed that male life expectancy had increased to 71 years from 48 in 1950. Women are now expected to live up to 76, compared with 53 in 1950.

Living longer brings with it its own health problems, as we age and deteriorate and our health systems are more heavily taxed.

According to IHME, heart disease was the leading cause of death worldwide. It was not until 1990 that neonatal disorders were the biggest killer, followed by lung disease and diarrhea.

Uzbekistan, Ukraine and Azerbaijan had the highest mortality rates due to heart disease, while South Korea, Japan and France were among the lowest.

& # 39; You see less mortality due to infectious diseases as countries get richer, but also more limitations when people live longer ,? said Mokdad.

He pointed out that deaths from infectious diseases such as malaria and tuberculosis have declined significantly since 1990, but new, non-transferable killers have taken their place.

& # 39; There are certain behaviors that lead to an increase in cardiovascular disease and cancer. Obesity is number one – it increases every year and our behavior contributes to this. & # 39;
