Around 60% of Poles and Polish citizens reside in urban areas or major cities and 40% in more rural zones. The most populous administrative province or state is the Masovian Voivodeship and the most populous city is the capital, Warsaw, at 1.8 million inhabitants with a further 2-3 million people living in its metropolitan area. The metropolitan area of Katowice is the largest urban conurbation in Poland with a population between 2.7 million and 5.3 million residents. The least populous and the smallest province in size is the Opole Voivodeship, with just under 1 million people living within its borders. Hence, a substantial portion of the total population is concentrated in the south of Poland, roughly between the cities of Wrocław and Kraków.
