How did government census data contribute to the early development of statistics?

Government census data and related vital records were foundational to the early development of statistics as a scientific discipline. In the 17th century, the English statistician John Graunt pioneered this field by analyzing parish death records, known as "bills of mortality," to identify regularities in human life and death. His work, which included the creation of the first life table, established the basis for demography and influenced the development of political arithmetic—a precursor to modern social science.1234

By the 18th and 19th centuries, the systematic collection of population data through regular censuses became a primary driver for statistical advancement. Governments utilized these counts for essential state functions, such as raising armies, taxation, and representative governance. This "rage for numbers" led to the emergence of "moral statistics," which sought to quantify social issues like crime, poverty, and disease. Figures such as Adolphe Quetelet further transformed these data into a mathematical science, arguing that probability was essential for understanding social laws and regularities.52
