In the census of November 2024, 80,647 people were counted in Água Grande, the district whose capital is São Tomé. In the 2012 census the city itself had 66,888 people, far more than any other town in the country.
Universalis: the Democratic Republic of São Tomé and Príncipe is the smallest African state, an archipelago of two islands (São Tomé, 859 km2, capital São Tomé; Príncipe, 142 km2, capital Santo António) and a few islets about 220 km northwest of Gabon; in 2010 the capital held more than a third of the country's 175,800 people.

Roofs, trees and a curving bay
Look at the big blue bay! Boats float on the water. Red roofs and green trees fill the town.
This photo shows São Tomé from the air on 19 February 2020. The photographer labeled it Ana Chaves Bay. The bay curves around in a wide arc, with small boats and a few ships on the calm water and long piers reaching out from the shore.
In front, wide roads meet at roundabouts between red-roofed houses, white buildings and many green trees. Far away, low hills rise on the left, and two small islands sit on the horizon at the right.

A Portuguese town that became a capital
Long ago, people from Portugal ruled these islands. In 1975 the country became independent.
Universalis describes São Tomé and Príncipe as former Portuguese colonies that became independent in 1975. Part of the islands' land, once covered in forest, was used for big plantation farms, called roças.
At independence, Universalis says, nearly all of the two thousand Portuguese settlers left. Today Portuguese is the official language, and many people speak forro, a creole language based on Portuguese.
Universalis: two small African islands in the Gulf of Guinea, former Portuguese colonies, independent since 1975; land originally covered in forest was partly used for plantation agriculture (roças), and deforestation and overuse have worn out and eroded soils. Society is described in groups whose boundaries are blurred: Filhos da terra (long-free, mixed-descent families), Angolares (descendants of Angolan workers), Serviçais (former contract workers from Africa) and Tongas (African immigrants); the two thousand Portuguese settlers almost all left at independence. Official language Portuguese; the spoken language is forro, a Portuguese creole.

Hot, wet and very green
São Tomé is warm and wet. It has a short dry time from June to September.
Because the islands lie just north of the equator, Universalis says, they have a humid tropical climate, with a short dry season from June to September. It gets cooler higher up the mountains.
The southern mountains get the most rain: their peaks, often wrapped in clouds, receive 4,000 millimeters or more a year. The highest is Pico de São Tomé, 2,024 meters high.

Forest, plantations and a shared language
People in São Tomé speak Portuguese and a language called forro. Rainforest with special birds covers the mountains.
In São Tomé people speak Portuguese, the official language, and forro, a creole language that grew out of Portuguese, Universalis says.
On the mountain slopes, the rainforest that was never cut down is home to plants and animals found nowhere else, especially birds. Elsewhere, part of the land was turned into plantations, and Universalis says cutting the forest and overusing the land have worn out and washed away the soil in places.
Universalis: on the slopes, the tropical forest that has not been exploited shelters a unique flora and fauna (birds); elsewhere the originally forested land was partly used for plantation agriculture (roças), and deforestation and overexploitation have favored soil exhaustion and erosion. Population 240,254 (2025) for the country; official language Portuguese; spoken language forro, a Portuguese creole.
City Population (census 2024): the country had 209,607 people, of whom 140,801 were counted as urban.
