# Katowice-Ostrava metropolitan area

The Katowice-Ostrava metropolitan area (also known as Upper Silesian-Moravian metropolitan area or Upper Silesian urban-industrial agglomeration) is a polycentric metropolitan area in southern Poland and northeastern Czech Republic, centered on the cities of Katowice and Ostrava, and has around 5 million inhabitants. Geographically, it is located mainly in Upper Silesia, with small parts of the area also in the historical regions of Moravia and Lesser Poland. Administratively, it is located in the three administrative units (NUTS-2 class): mainly Silesian Voivodeship and a small western part of Lesser Poland Voivodeship in Poland, and also a small eastern part of Moravian-Silesian Region in the Czech Republic.
The metropolitan area lies within the Upper Silesian Coal Basin. The Upper Silesian metropolitan area (5.3 million people), together with nearby Kraków metropolitan area (1.3 million people) and Częstochowa metropolitan area (0.4 million people), create a greater Kraków-Katowice-Ostrava metropolitan region [Wikidata] covering 7 million people.

## Demographics

Upper Silesian metropolitan area has a population of 5,294,000 (2002), with 4,311,000 (81.43%) in Poland (the Upper Silesian polycentric metropolitan area) and 982,000 (18.57%) in the Czech Republic (Ostrava Functional Urban Area). According to Polish Scientific Publishers (PWN) area is 5,400 km², with 4,500 km² (83.33%) in Poland and 900 km² (16.67%) in the Czech Republic. According to the Brookings Institution, area has a population of 5,008,000 (2015).
The area consists of several Functional Urban Areas (FUA), each of which is defined as a core Morphological Urban Area (MUA) based on population density plus the surrounding labour pool, i.e. a metropolitan area. This area contains the following FUAs:
* Katowice FUA: 3,029,000; within Upper Silesian Industrial Region
* Ostrava-Cieszyn FUA: 1,046,000; within Ostrava-Karviná coal basin [Wikidata]
* Bielsko-Biała FUA: 584,000; within Bielsko Industrial Region
* Rybnik FUA and Racibórz FUA: 634,000 (526,000 + 109,000); within Rybnik Coal Area

## Economy

Historically, most of the area was characterized by heavy industry since the age of industrialisation in the late 19th and early 20th century. In addition to coal, Upper Silesia also contains a number of other minable resources (methane, cadmium, lead, silver and zinc). About 70 billion tons of coal resources are available up to a depth of 1000 meters and the conditions for extraction are good.
Contrary to most other European cross-border polycentric metropolitan regions, Katowice-Ostrava has no established cross-border cooperation project, structure, or institution of metropolitan ambition.

## Transport
