The hottest Population Growth Substack posts right now

India's population growth is slower than perceived, with the Total Fertility Rate (TFR) below replacement level, indicating a declining birth rate. This trend is expected to continue with further development.
With decreasing birth rates, India faces the challenge of an aging population, leading to potential increases in death rates. The country's median age is rising rapidly compared to global averages.
Despite being highly populated, India's net migration rate remains close to 0, indicating that migration is not a significant factor in the country's population dynamics. Population decline in India is projected to begin in the mid-2060s.

Increasing population growth is crucial for economic and technological progress
People have increasing returns and can drive economic growth by sharing ideas
Population growth is fundamental for economic growth and technological progress based on empirical evidence

Climate change plays a significant role in the drying up of lakes, streams, and rivers around the world.
Human activities contribute to the water level decline in water bodies, along with climate change.
As the world's population grows, the stress on water resources, migration, and conflicts due to drying water bodies could increase.

Africa's population is projected to reach 40% of the world's population by 2100, having significant implications in various aspects.
There's a generational shift happening in Africa as Baby Boomers recede, and younger generations come into power with different values and priorities.
Despite potential migration desires, many young Africans want to stay in Africa to make a positive impact, potentially reshaping the continent's future.

Social media has greatly influenced society and its bans would bring rapid change.
Technology developments must be considered with an understanding of values, tools, and actions in achieving societal goals.
Lessons from historical movements like Romanticism and Ecology can guide discussions on technology and society today.

Murray Bridge in Australia is preparing for significant population growth and planning major changes like new schools and street renovations.
In the short term (zero to five years), there are plans to improve infrastructure like water sports parks, rezoning for development, and renovating the swimming pool.
In the long term (10+ years), Murray Bridge is considering a new ring road, expanding Mobilong Prison, and space for up to 19,000 new homes as the population grows.

Rising home prices are mostly from rising rents due to supply constraints
Price/income ratio is a valuable indicator for evaluating housing supply elasticity
Credit access and supply constraints play significant roles in home price changes

Having more people is not inherently bad; each new person brings potential for creativity and productivity.
Limiting lifespan extension to control population growth is ethically irresponsible and ineffective; focusing on reducing birth rates is a better approach.
Global population growth is projected to slow and eventually decline due to various factors, including declining fertility rates and aging populations.

Comparing housing growth to population growth may not reveal housing supply constraints.
There is a cyclical relationship between housing growth and population growth in different cities.
Supply constraints lead to combative consumption and disproportionately affect the less advantaged.

Critics of open borders argue about moving costs, either saying they are too high or too low, but over time, open borders can have a positive impact.
Existing examples show that migration patterns can change gradually, with diaspora reducing migration costs over time.
A model for open borders suggests that allowing migration can lead to population growth without negatively impacting the destination country's institutions, potentially lifting billions out of poverty.
