The 1934 yearbook contained detailed information about agriculture, particularly in regard to the surface area devoted to fruit trees, the state of zootechnics and the number of tractors.

Examples include the use of economic resources, gross domestic product, national wealth, energy, housing and income, spending and consumption of the populace.
