Which is not true about changes in the US population between 1870 and 1890?

Between 1870 and 1890, one common misconception is that the overall population growth was solely due to natural increase. In reality, a significant portion of the population growth during this period was driven by high levels of Immigration, particularly from Europe. Additionally, while urbanization increased, rural populations also remained substantial, contradicting the notion that the entire population was moving to cities. Lastly, the demographic shifts included not only an increase in numbers but also changes in the ethnic and cultural composition of the population.
