Peru's per-capita growth rates have diverged from overall growth rates over the last quarter-century. Peru's GDP per capita peaked in 1981 and is only recently on the path to return to that level. By the end of 2006, the government had enacted measures that allowed the economy to improve by increasing investments, and expanding production and exports. Raw materials and agroindustrial products represent the bulk of potential exports. By 2020, investment is expected to total US$25 billion for mining activities; US$20 billion in energy, especially petroleum; US$12 billion for commerce; US$8 billion for agricultural industries; and US$5 billion for tourism.
