The two processes are the formation of national states and the growth of statistical science. With the advent of the modern age, national states came up in Europe as important political organizations. With this, the role and responsibility of the modern nations began to increase. For example, administering public health, economic policies related to manufacturing and industry, tax, its collection, increasing incomes, urban management – all these needed the attention of the nation.
The growth of numerical (statistical) science was also important. As the areas of activity of nations increased, there was a need to have precise statistical data. Statistical data were needed in the case of population and economic systems with regard to their number, size and measure.
