Seriously. Why are we making videos like this? This topic was a nightmare. How do you talk about a continent as diverse as Africa, to explain larger trends? Not only is there a wide variety of sources, experts disagree with each other on what they can predict about the future. So the time we took to rewrite this script over and over was insane.
Still, there is no chance in hell this video won’t make people angry, on all sides of this issue. Some may not agree with the conclusions we have come to. Some will think there are other aspects we could and should have mentioned. Or lament that we generalized too much.
But we had to generalize or this video would just have become an hour-long documentary. And we think the topic is too important to not discuss it.
So we read a lot and talked to many experts with very different opinions and interpretations on the subject. Also we tried to prepare our sources in a way that walks you through our thought process and helps you to make up your own mind.
This video was sponsored by the Bill & Melinda Gates Foundation as part of a Grant. The Foundation did not comment on the video in any way before we released it.
A huge thanks to the following scientists and experts for their input and help with this video:

– While some projections expect around 2.6 billion people others reckon with up to 5 billion by 2100.
The optimistic projections were made by the IAASA (International Institute for Applied Systems Analysis)

There are new numbers from 2018, but these projections only look as far into the future as 2060:
#Demographic and Human Capital Scenarios for the 21st Century: 2018 assessment for 201 countries, 2019
The population of Sub-Saharan Africa, on the other hand, is likely to more than double by 2060 from currently around 1 billion to 2.2 billion under the Medium scenario and even 2.7 billion under the stalled development SSP3 scenario.
The more pessimistic ones are by the UN:
#World Population Prospects 2019, UN, 2019
https://population.un.org/wpp/
If you don't want to go through the trouble, we downloaded the 2019 Excel Spreadsheet for you. Here is a screenshot. The red line is the median projection with 3.8 billion and the pessimistic 90% prediction interval comes up with almost 5 billion.
This table shows all three projections:
https://blog.wp.iiasa.ac.at/wp-content/uploads/sites/5/2015/10/table-1.png
A quick side note here: you might be wondering why there are multiple projections that are so different. That is because trying to make predictions about the future is tricky.
Population growth rates depend on how many children are born and how many survive. The UN and the IIASA both agree that child mortality will go down. The difference is: they make different assumptions about how many kids the average African woman will have in the future.
The UN is assuming that this trend will continue because fertility all over Africa has declined slower than in other parts of the world. The IIASA assumes that fertility rates will adapt to the same development patterns that happened all over the rest of the world – which would mean fertility will decline faster than it did in the past.
The IIASA bases their claim on the fact that they take women’s education levels – an important factor for their family planning decisions – and country-specific features into account.
For any projection, even a small difference in children per woman already makes a big difference for population numbers when the effect is viewed over several generations.
This article from Our World in Data covers the importance of African population projections using the IIASA projections:

– But Sub-Saharan Africa is also the poorest region on earth.
In terms of financial aspects, extreme poverty means to have less than 1.90$ per day.
#Ending Poverty, 2019

In Sub-Saharan Africa up to 42% of the population continues to live below the poverty line. This is around 71% of all extremely poor people in the world:

Hunger, poor health and a lack of education are also manifestations of poverty.

The International Monetary Fund (IMF) measures the economic growth of all countries. The link to the official numbers of the IMF was half a page long so we turned it into a bitly-link:

The IMF came up with new numbers for 2019 shortly before the release of this video: In 2019 there are still three Sub-Saharan countries among the five fastest growing economies in the world, but not the same ones as in 2018. This chart shows the fastest growing countries of the past years:

– A few decades ago, many countries in Asia were at a similar point as Sub-Saharan Africa today: Large parts of the population were living in extreme poverty and birth rates were very high.
This report from the Berlin Institute for Population and Development analyzes in detail which countries have made progress in poverty reduction and development in the past and how those factors correlated with fertility rates.

– So beginning in the 1960s Bangladesh started a family planning program, standing on three main pillars:
Here we simplified a lot: First of all, Bangladesh gained independence in 1972, before that it was part of Pakistan. The family planning program we refer to in the video actually consists of several so called “five-year plans”.
The first and the second five year plan were established by the Pakistani government in the late 1950s and early 1960s. Since the independence in 1972 there have been seven five-year plans introduced by the Bengali government.
These plans include a lot more than the three pillars we speak about in the video. The major part of the investments were spent on infrastructure, water-supply and housing, but regarding family planning, the crucial pillars were education, better health care and contraception:
This is the revised second five-year plan introduced by the Pakistani government:
#Pakistan – The revised second plan (1960 _1965)
http://documents.worldbank.org/curated/en/750571468286258544/pdf/multi0page.pdf
“The Government estimates that the expenditures in the Second Plan will be some 250% above the actual expenditures during the First Plan period.”
Compared to the first five-year plan, the investments in education and health increased drastically.
Here you can download the full plan, but we took some screenshots for you:

documents.worldbank.org/curated/en/991321468768584526/pdf/multi0page.pdf
At the same time, the government got aware of the increasing importance of family planning and created a Department of Family Planning.
#Agenda-Setting of Population i Bangladesh and West Bengal and impact on Fertility, 2012
https://paa2012.princeton.edu/papers/121206
“Under the Third Five Year Plan (1961-1966), 92% of allocation was spent, the Department of Family Planning was created within the Ministry of Health, andFP services were integrated with MCH services.”
The measurements of the freshly created department can be grouped into three phases:
#Family Planning in Asia and the Pacific Addressing the Challenges, 2010
http://www.icomp.org.my/new/uploads/fpconsultation/Bangladesh.pdf
“Phase 1 activities were largely voluntary, beginning in the early-1950s. Phase II activities began in 1960, with the government taking some broader steps to check the population growth rate. Population control was made the official policy in the First Five-Year Plan of Pakistan (1960-65). Phase III activities were initiated in 1973 with the launching of the First Five-Year Plan of Bangladesh. The Plan attached equal priority to population control and food production. It marked the beginning of a multi-sectoral and broad-based population control and FP programme in the country.”
This study looks at how Bangladesh and Pakistan developed regarding family planning after they became two separate countries.

– Field workers brought contraceptives even to the remotest areas, which drove contraceptive use from 8% in 1975 to 76% in 2019.

#Adding it Up: Costs and Benefits of Meeting the Contraceptive Needs of Adolescents in Sub-Saharan Africa, Factsheet from Gutmacher Institute, 2018
Among the 53 million women aged 15–19 in Sub-Saharan Africa, 23% (12.1 million) need contraception because they are married, or are unmarried and sexually active, and do not want a child for at least two years.
Of these 12.1 million adolescents, 38% (4.6 million) are using modern contraceptives. The most common method is the male condom (accounting for about four in 10 users), followed by injectables and the pill.
The other 62% (7.5 million) are not using a modern method; these adolescent women have an unmet need for modern contraception. Among these women, 87% are using no method at all, and the remainder use traditional methods, which are less effective than modern methods.
– Many Sub-Saharan Nations have suffered under colonization until only a few decades ago, and had rough transition periods towards independence.
This article by the World Economic Forum highlights the long-term effects of colonization on African economies:

–The young nations were often ethnically heterogeneous and lacked unity. Some areas have been repeatedly racked by civil wars, military conflicts or suffered under unstable governments, which made it really hard to expand infrastructure and health care.
Each African country has its own history towards independence. We picked a couple of examples for national conflicts that occured in the second half of the 20th century.
One of the most horrific examples for ethnic conflicts in African countries is the genocide in Rwanda. In 1994 more than 800,000 Tutsis were killed by Hutu extremists.
#Rwanda genocide: 100 days of slaughter, 2019

The World Atlas offers an overview on the different ethnic groups of Rwanda:
#Ethnic Groups Of Rwanda, 2017
https://www.worldatlas.com/articles/ethnic-groups-of-rwanda.html
Another example is South Sudan, which gained independence in 2011. Since 2013 a bloody civil war is going on in the youngest country in the world.
#Global Conflict Tracker, 2019
https://www.cfr.org/interactive/global-conflict-tracker/conflict/civil-war-south-sudan
As a consequence of these conflicts the governments in those countries were very unstable and not able to guarantee safety and good living standards.
Eritrea gained independence in 1991 after 30 years of civil war with Ethiopia. Ethnically, Eritrea is one of the most diverse countries in the world:

– Foreign aid and how it was applied, especially during the cold war, is also a contentious issue.
This magazine on political science summarizes the debate on foreign aid in third world countries:
#Economic development and the effectiveness of foreign aid: A historical perspective, 2014
https://voxeu.org/article/development-and-foreign-aid-historical-perspective
This paper reviews the economic literature on foreign aid and highlights the disagreement among researchers.

https://mpra.ub.uni-muenchen.de/82134/1/MPRA_paper_82134.pdf
“Aid supporters tend to emphasize results, while its detractors tend to highlight the incentives it provides (although they may still acknowledge some of aid’s positive results, particularly on public health)”
Many scientists argue that especially during the Cold War foreign aid was driven by ideological motives, rather than a true interest in helping African countries:

– If population growth continues unhindered at its present rate then Sub-Saharan Africa could grow to 4 billion people. For example, if women get a better education and have their first child just two years later in life. This tiny gap between this generation and the next one would lead to 400 million fewer people in 2100, with 3.6 billion in total. If education and family planning are made available to every African woman, universal access to contraception makes having kids a decision. If families get to choose how many kids they want, birth projections fall by 30%, to 2.8. billion people.
All numbers from the text passage above are based on three different scenarios modeled by the Track 20 project. They compare different interventions on population development and calculate the results.
#Track20
http://www.track20.org/pages/about_us/who_we_are/Track20.php
Scenario 1 (The black line in the infographic):
“If population growth continues unhindered at its present rate then Sub-Saharan Africa could grow to 4 billion people.”
Scenario 2 (The pink line in the infographic):
“This tiny gap between this generation and the next one would lead to 400 million fewer people in 2100, with 3.6 billion in total.”
Scenario 3 (The blue line in the infographic):
“If education and family planning are made available to every African woman, universal access to contraception makes having kids a decision. If families get to choose how many kids they want, birth projections fall by 30%, to 2.8. billion people.”
The scenarios are discussed in detail on page 13 of the Goalkeepers Report 2018:

– Ethiopia, the African country with the second-biggest population, has made a lot of progress in a relatively short amount of time. Improving health services lead to a drop in child mortality from 20% to 7% since 1990.
Ethiopia is on track to be the first low-income African country to achieve SDG1 (Sustainable Development Goal 1: end poverty). We forecast that by 2029 less than 3% of Ethiopia’s population will live in extreme poverty.
