About - Ostrołęka

Ostrołęka, with about 50,000 residents in Masovian Voivodeship, is a sub-regional centre on the Narew River near the Podlachian border, known for power generation (Ostrołęka Power Plant) and the paper industry (Stora Enso). Strengths: a dense network of sports clubs (6.7 per 10,000, 92nd percentile), low property crime (8.74 per 1,000, 92nd percentile), full sewage coverage (99.9%, 91st percentile), high police effectiveness at 78.3% (85th percentile) and a high birth rate of 7.05/1,000 (83rd percentile). Favourable demographics (natural increase -2.04/1,000, 89th percentile) set Ostrołęka apart from ageing cities. Weaknesses: minimal library readership (4,781 readers, 2nd percentile), just 1 stadium (5th percentile), high road fatalities (4.17 per 100,000, 5th percentile), a thin tourism base (137 tourists per 1,000, 4 hotels) and a low new-business count (390, 11th percentile). Gross wages of PLN 8,537 (99% of the national average) are attractive, but unemployment of 7.5% remains high. Ostrołęka offers strong demographics and safety, but needs development of its tourism and cultural sectors.
