Abortion now a significant demographic parameter

January 15, 2019

During 2018, it is estimated that around 140 million babies were born and that around 60 million people died. The global population had reached 7.7 billion at the end of 2018.

In addition, around 41 million legal abortions were carried out in 2018. There may also be a significant number of illegal or unreported abortions so that the total number may be around 50 million.

Global fertility rates are declining inexorably. The number of babies born will be reducing over the next 100 years (with the biggest declines expected in Africa). The crude death rate is a balance between two trends; first the decline due to improving health care (and longevity) and second the increase due to an increasing population of the aged. By around 2090 deaths will exceed births and by 2100 the world population will be in decline.

Abortions are not recorded in either birth or death statistics. But what is not in doubt is that the actual number of babies born is almost 30% lower because of abortions. If abortions were included in both birth and death statistics the natural population increase (births minus deaths) would remain unchanged (190m-110m instead of 140m-60m). However, abortions would then be the single highest cause of death. The next highest cause of death would then be coronary artery disease (around 10m).

The long term, global, fertility and morbidity trends are not affected by the number of abortions. Even if no abortions took place, world population would still stabilise and then decline but this would be delayed by about 40 years (stabilisation and decline in 2130 instead of about 2090).

That abortion is now a significant demographic parameter is self-evident.

The morality or rightness of carrying out abortions is a different matter and primarily for women to decide on. The human species is the only one which has the ability to, and does, carry out intentional abortions. That women should be assisted to carry out abortions to preserve their health or for other necessary medical reasons (physical or mental) seems obvious.

I am not so sure that assisting abortions for the convenience of the mother or for covering up carelessness is equally justified. Or that 41 million legal abortions is a number to celebrate or to be particularly proud of.

Fewer children under five dying than ever before

September 16, 2017

The 2016 GBD study is out at The Lancet.

The Global Burden of Disease Study (GBD) is the most comprehensive worldwide observational epidemiological study to date. It describes mortality and morbidity from major diseases, injuries and risk factors to health at global, national and regional levels. Examining trends from 1990 to the present and making comparisons across populations enables understanding of the changing health challenges facing people across the world in the 21st century.

One section deals with Mortality, and of major significance is the deaths of children (< 5 years). Around 4.6%  – 340 million – of the worlds population of 7.5 billion is under 5 (UN World Population Prospects 2017). Death is becoming the preserve of the old – as it should be. In the last 50 years, death has shifted decisively away from children to the aged.

 

About 5 million recorded deaths in 2016 were of children under 5 and had reduced from about 16 million in 1970. In that time the total number of children <5 has doubled. In 2016, deaths of children < 5 has reduced to one-sixth of the proportion in 1970. Almost two-thirds of all deaths are now at ages above 50 years. There are, for the first time, more deaths at ages above 75 than between 50 and 74 and, it would seem, is poised to increase sharply.

About 40% of the world’s population (60% in Africa) is now under 25 years old. The vast majority of them will live to see 75.
