The 1830 Census Index for U.S. Selected Counties provides a snapshot of the United States during a pivotal time in its history. Conducted as part of the decennial census, this particular data collection focused on selected counties across various states. The information gathered included the population count, categorized by age, sex, and race. Unlike modern censuses, which are far more comprehensive, the 1830 Census was more straightforward but still served an essential role. It helped the government plan and resource allocation while providing valuable information to researchers, historians, and genealogists. Importantly, it reflects the socio-economic conditions of the era, including the contentious issue of slavery. This census remains a crucial historical document for anyone studying the growth and demographics of the United States in the early 19th century.
