from 211,169 in 2001 (highest) to 202,562 in 2018. Among the demographic trends influencing this decline, are: suburbanisation, migration to larger urban centres, and wider trends observed in the whole of Poland such as general population decline, slowed down by immigration in 2017. The birth rate in the city in 2017 was 0.75. Low birthrates have been consistent in the city for the first two decades of 21st Century. The official forecasts from Statistics Poland state that by 2050 the city population will have declined to 157,949. Inside the city itself, most of the population is concentrated on the right (northern) bank of the Vistula river. Two of the most densely populated areas are Rubinkowo and Na Skarpie, housing projects built mostly in the 1970s and 1980s, located between the central and easternmost districts; their total population is about 70,000. The Bydgoszcz–Toruń metro area of Toruń and Bydgoszcz, their counties, and a number of smaller towns, may in total have a population of as much as 800,000. Thus the area contains about one third of the population of the Kuyavia-Pomerania region (which has about 2.1 million inhabitants). Transport The transport network in the city has undergone major development in recent years. The partial completion of ring road (East and South), the completion of the second bridge (2013) and various road, and cycling lane improvements, including construction of Trasa Średnicowa, have decidedly improved the traffic in the city. However, noise barriers that have been erected along the new or refurbished roads have been criticised as not conducive to a beautiful urban landscape. The extensive roadworks have also drawn attention to the declining population numbers, casting doubt that the city might over-delivered for the future number of road users, as the demographic trends forecast from Statistics Poland predicts a reduction of population by almost 1/4 by year 2050. The city's public transport system comprises five tram lines and about 40 bus routes, covering the city and some of the neighboring communities. Toruń is situated at a major road junction, one of the most important in Poland. The A1 highway reaches Toruń, and a southern beltway surrounds the city. Besides these, the European route E75 and a number of domestic roads (numbered 10, 15, and 80) run through the city. With three main railway stations (Toruń Główny, Toruń Miasto and Toruń Wschodni), the city is a major rail junction, with two important lines
