As agriculture underwent modernization in the 1970s and 1980s, soil fertility became less important for agricultural production than factors related to capital investment, such as infrastructure, mechanization, use of chemical inputs, breeding, and proximity to markets.
Consequently, the vigor of frontier expansion weakened.

In 1990, 6.6% of the region's territory was considered altered by anthropic (man-made) action, with state levels varying from 0.9% in Amapá to 14.0% in Rondônia.
In 1996 the North had 11.1 million inhabitants, only 7% of the national total.
However, its share of Brazil's total had grown rapidly in the 1970s and early 1980s as a result of interregional migration, as well as high rates of natural increase.

Its total area of corresponds to 10.9% of the national territory.
The region has the largest share of the country's population, 63 million in 1991, or 39% of the national total, primarily as a result of internal migration since the mid-19th century until the 1980s.
In addition to a dense urban network, it contains the megacities of São Paulo and Rio de Janeiro, which in 1991 had 18.7 million and 11.7 million inhabitants in their metropolitan areas, respectively.
The region combines the highest living standards in Brazil with pockets of urban poverty.
In 1994 São Paulo boasted an average income of US$4,666, while Minas Gerais reported only US$2,833.
Originally, the principal biome in the Southeast was the Atlantic Forest, but by 1990 less than 10% of the original forest cover remained as a result of clearing for farming, ranching, and charcoal making.
Anthropic activity had altered 79.7% of the region, ranging from 75% in Minas Gerais to 91.1% in Espírito Santo.
