The average US income in 1950 was approximately $3,300 per year. Adjusted for inflation, that's roughly equivalent to $42,000 in 2025 dollars.
The median US home price in 1970 was about $23,000. That same home would cost roughly $350,000-$400,000 today — a 15-17x increase.
The world population in 1900 was approximately 1.6 billion people. It took until 1927 to reach 2 billion — and then exploded to 8 billion by 2022.
