Prior to COVID, many projections had the world's population plateauing sometime in the second half of the 21st century. This is expected to happen because about half of the world's population now lives in a country where the fertility rate is less than the replacement rate of 2.1 children for every woman. See above chart from The Economist.
At the start of the pandemic, there was talk of a possible COVID baby boom. People were/are stuck at home and so that would surely translate into more sex among partners. But that doesn't appear to have been the case for many countries. According to The Economist, births fell by 15% in China last year. The same drop was recorded in the United States last year between February and November.
Because of this trend, the above projections are now being adjusted and pulled forward, with some predicting that the world's population could plateau as early as the 2050s. That's only about 30 years from now, which means that quite a few of us could end up living in a world with a declining population. This is likely to have both positive and negative consequences.
There are nearly 8 billion people in the world today with China and India being the countries with the greatest numbers. But it's interesting to consider how recent this figure really is (compounding takes time to gain momentum).
The world didn't hit a billion people until the 19th century, and the second billion was only reached by the 1920s, which in the grand scheme of things, isn't that long ago. Since then the global population has exploded with about 6 billion people being added in only the last 100 years. That's pretty wild when you think about it.
P.S. I recently discovered a site called outline.com. It allows you to read, highlight, and annotate articles that you find online. But it also seems to allow you to read articles behind paywalls. Perhaps some of you will find that useful.

At the beginning of this year, Singapore expanded its preschool subsidies and improved its support for assisted reproduction and fertility treatments. The goal: more Singaporean children. According to the World Bank (via the Wall Street Journal), Singapore has one of the lowest fertility rates in the world at about 1.14 children per woman as of 2018. This is down from about 3 in 1970, when the government was actually worried about the opposite problem -- too many children.
Of course, this trend is not unique to Singapore. This is generally the way the winds are blowing in the developed world. Young people are spending more time on education, career, and travel. And they're delaying marriage (or not getting married). On top of this, family-sized housing has become fairly expensive in most big cities. The fastest solution is to ramp up immigration, but many countries, including Singapore, have concerns about what this does to the "national identity."
Newly released data from the US Census Bureau has just revealed that the average household size is increasing for the first time in over 160 years. Put differently, the formation of new households has started to trail overall population growth. And that is causing the average number of people per household to increase.
In 1790, there were about 5.79 people per household in the United States. That number has been in decline pretty much since then, though there was a slight increase in the decade that began in 1850. Last year (2018), the number grew to 2.63 people per household (2.71 for owner occupied households and 2.48 for renter occupied households).
Here are two charts from Chris Fry's recent piece at the Pew Research Center:
So what is causing this?
Well, we know that US fertility rates aren't on the rise. In fact, they're generally viewed as hitting record lows. I say "generally" because there are a number of different ways to measure fertility. There's the general fertility rate, completed fertility, the total fertility rate, and others. But we are seeing some alignment here: fertility rates are down.
One probable explanation is the fact that more Americans are living multi-generationally. According to the Pew Research Center, 1 out of every 5 Americans lived in such a household as of 2016. Part of this may be a result of immigration. Asian and hispanic populations are more likely to live in a multi-generational household compared to white people.
Another demographic trend is the increase in people living in shared quarters, whether that might be with a roommate or someone else. This is interesting because it suggests that there's an affordability constraint. Are people being forced to "double up?" The current co-living trend is at least partially because of this.
These are all noteworthy trends because household formation is viewed as "the underlying driver of long-term demand for new housing." I am assuming that more people per household also means less square footage per person.

So there seems to be a preference for throwing money at the problem and promotional material with slogans like this one: "Have three, or more if you can afford it."
