There is a correlation between baseball and population, but it is not a direct causal relationship. It is more accurate to say that baseball is a reflection of the population and cultural trends in the United States.

As the population of the United States has grown, so has the number of baseball fans. This is due to the fact that baseball has been a popular sport in the United States for over a century, and it has been widely played and watched across the country.

However, baseball has also faced competition from other sports such as football, basketball, and soccer. The popularity of these sports has grown in recent years, and they have started to take away some of the attention that baseball once had.

Overall, while there is a connection between baseball and population, it is just one of many factors that influence the popularity of the sport. Other factors such as cultural trends, marketing, and competition from other sports also play a significant role in the success of baseball.
