"United States Census Figures Back to 1630" by the United States Bureau of the Census is a statistical publication likely compiled in the late 20th century. The work presents historical population data for the United States, extending back to its early colonial days and aiming to provide insights into demographic trends over time. The opening of the publication discusses the methodology behind compiling the census data, including the averaging of figures from various sources and the adjustments made for estimates post-1992. It highlights the significance of understanding these statistics within the context of inflation and population growth, especially as it relates to educational attainment. The authors emphasize the necessity of careful demographic analysis to derive meaningful conclusions from the population figures presented in the accompanying tables, cautioning against oversimplified interpretations of increases or decreases in statistics that do not consider population growth rates.
