Many countries, including the USA, have birthrates that either are too low to sustain current population levels or are stable. Since 1970, the population of people born in the USA has been stable at below 300 million. In fact, some estimates show a decline in population. All of the population growth in the USA during this time period has been due to immigration. That is why the USA has grown to 336 million people in 50 years. This trend has only increased in recent years.
There were a record 44.8 million immigrants living in the U.S. in 2018, making up 13.7% of the nation’s population. This represents a more than fourfold increase since 1960, when 9.7 million immigrants lived in the U.S., accounting for 5.4% of the total U.S. population.
For Jill and I growing up in a blue state, we were indoctrinated at an early age by the public school system that having two children was the responsible thing to do to save the planet from overpopulation. That careers were more important that having a large family. That women would find more fulfillment in a education and career, as opposed to staying at home. That women should defer motherhood until college and a career were firmed established. That this was the responsible path to take. Today, young women receive the same messaging from our government, our schools systems, and main stream corporate media.
