The leading employment sectors in Peru have long been agriculture and fishing, mining, and manufacturing, while the services sector was relatively undeveloped. As the population and economy grew in the latter half of the 20th century, the percentage of agricultural workers declined, the mining and manufacturing sectors were relatively stable, and the services sector grew rapidly, employing some three-quarters of the workforce by the early 21st century. However, between 1980 and 1990, wages in Peru fell dramatically; the average manufacturing wage, for example, dropped by almost two-thirds. Although wages did increase in the 1990s, they were still well below 1980 levels at the end of the 20th century. As a result, few workers earn above the official poverty line, and many must work multiple jobs to make ends meet. Unionized workers in the mining and government sectors have done better than those employed in other areas.

A large percentage of Peruvian workers are employed in the “informal” economy, outside government regulation and taxation and without the protections offered by legal employment. Workers in the informal sector include street vendors, those employed in small workshops in squatter settlements, drivers of jitney taxis in larger urban areas, and women making tourist trinkets in their homes. Most informal workers are underemployed in jobs that provide only a limited amount of work (and income) per week.

From the mid-1990s, significant investment in the tourism sector has led to improvements in the country’s economy. Further growth of this sector is anticipated as the government promotes policies to develop tourist infrastructure in various parts of the country.

Transportation and telecommunications

Peru’s transportation system faces the challenge of the Andes and of the complex Amazon River system. River traffic in Amazonia is underdeveloped because of the vast distances and low population density of that area. Roadways cross the country from north to south, or they form penetration roads that run east–west over the Andes. The most important road is the Pan American Highway, which parallels the coast from Ecuador to Chile. Other main roads include the trans-Andean, or Central Highway, which follows the Rimac River Valley east from Lima, crossing the Andes and connecting to the Mantaro Valley near Huancayo, and another main road that connects Arequipa to Bolivia through the Andes.

The major Peruvian railroad, the Central Railway, rises from the coast at Callao near Lima to cross the continental divide at about 15,700 feet (4,800 metres). It connects with a branch line to Cerro de Pasco, making it of great importance to the mining industry of the central Andes. A longer line, the Southern Railway, serves Cuzco, Arequipa, and other cities and ports such as Puno on Lake Titicaca; some of its traffic originates in Bolivia. Callao, on the Pacific Ocean, is the largest of Peru’s numerous ports. Iquitos, located on the Amazon some 2,300 miles (3,700 km) from the river’s mouth, is the major river port of eastern Peru.

The rough terrain of Peru compels the use of the airplane, but it also complicates flight. Air transport is especially important in hard-to-reach places of the heavily forested east. Commercial aviation began in 1928, and several domestic companies operate in addition to numerous foreign airlines. Jorge Chávez International Airport, which serves Lima, is the most important of Peru’s airports. Arequipa, Cuzco, and Iquitos are served by international airports as well.

Landline telephone service in Peru is generally of adequate quality, and usage continued to increase from the early 1990s into the 21st century. The use of mobile phones skyrocketed during that same period of time, and usage surpassed that of the traditional land telephone service. Internet service, although limited, began to expand steadily at the beginning of the 21st century.
