How many people have just one child?

We plan to start a family later this year and had always thought we’d like to have at least two kids, but more and more of our friends are only having one child and then saying they’re done? It’s for various reasons, but mainly citing space in homes (many people still living with family, or renting small apartments), cost of living and childcare costs, and a few just hated being pregnant.

For those who have started a family in the last 2-3 years, what are your thoughts? How many kids have you / do you plan to have? Just curious.
