This map of Brazil was drawn by Manoel Paulino Calvacanti in 1908 for the Agricultural Geography Section of the National Agricultural Society of Brazil.
The map provides a description of the country's main cities, the capitals of each of the states, and the state capital, Rio de Janeiro, at that time. It also includes the state borders and the course of the main rivers, but the map is primarily demographic in nature, with three colours denoting the population density of the country at that time:
- Yellow: Density of less than 1 inhabitant per square kilometre.
- Green: Density between 1 and 10 inhabitants per square kilometre.
- Red: Density between 10 and 20 inhabitants per square kilometre.
At the bottom left, there is also a small graph showing the weight of Brazil's population compared to the rest of South America, with 22 million inhabitants compared to Argentina's 6 million or Peru and Colombia's 4 million.
