Szukana fraza: [Abstract = "There has also been a reduction in built\-up areas, though it is considered that, with little interchange between the two populations, the two declines are not directly related. The urban decline did not become obvious until about 1990, where in the centres of some large towns the decline, unlike that in farmland, took place at an increasing rate leading to virtual extinction. Closer examination shows that the situation in the built\-up areas is far from uniform, with a similar decline to that in the urban centres occurring in the so\-called \"leafy affluent suburbs\", but any decline being much less pronounced in the inner residential areas and modern housing estates."]
