The province is surrounded by the provinces of Tapacarí in the northwest, Quillacollo in the northeast, Capinota in the east, Bolívar in the south and the departments of Oruro in the west and Potosí in the southeast.
It is located in the Bolivian Andes at an elevation between 3,000 and 4,500 metres and about 250 km west of Cochabamba, the capital of the department. The landscape is deeply fissured. Some of the highest mountains of the province are listed below:
The rainy season covers the months from December to April. The precipitation can occur in the form of devastating hailstorms which may even destroy the planted seeds of field crops and the harvests.
Arque Province is divided into two municipalities (Spanish: municipio, sección or sección municipal): Arque Municipality (first section) and Tacopaya Municipality (second section). The two municipalities with one mayor each are further subdivided into four cantons and supervised each of them by a corregidor: Arque Canton and Colcha Canton in Arque Municipality and Tacopaya Canton and Ventilla Canton within Tacopaya Municipality. The province is managed by a sub-prefect (subprefecto).

Arque Municipality is situated in the eastern part of the province and Tacopaya Municipality is located in the west.
Arque Province has the lowest Index on Human Development (0.311)  within Bolivia. Of all the 314 municipalities in Bolivia Arque was on the last position (HDI 0.311) in the year 2001 and Tacopaya was on rank 308 (HDI 0.361). However, in recent years many measures particularly done in the field of education and health have been taken in order to improve the social situation. In 2005 92% of the population of Arque including larger and smaller communities had access to potable water according to reports from Arque Municipality. Only seven communities still remained without water supply at that time.
The province has a rural character. Most families rely on subsistence farming for their livelihood. The peasants cultivate maize, wheat, barley and potatoes on the stark, steep slopes. The population with a high number of indigenous citizens of Quechuan and Aymara descent  mostly lived or still lives in humble houses with earthen floor, adobe walls, roofed with thatched material. Often these houses only consist of one single room where the meals are prepared on open fire so that the smoke can cause infections of the eyes. The roofs bear a deadly danger which comes overnight: the blood-sucking winchuka bugs (vinchuca), common to the zone, which can cause the Chagas disease. During the day the insects hide in crevices in the walls and roofs made of straw. The bugs emerge at night, when the inhabitants are sleeping. One measure to reduce the risk of acquiring the disease is the renovation of houses by using tiles and the construction of houses that are resistant to the entry of the bug.
