Why factories are not located in Inner-city areas any more?

During 1951 to 1991 there was an obvious economical decline in industries, which were based in the inner-metropolis areas. Inner-city areas experienced a considerable decline in industry during this time. All of the following resulted in the ending of factories, offices and shopsIndustries were expanding at such a rate that they were taking up completely the room in the inner-city areas. As we already know there is express room in the inner city, and it would have been impossibility for the industries to expand each more. If they did expand, it would mean that they were expanding into residential areas, which is another impossibility. Once the factories had reached their full capacity in the areas they were situated, they were forced to move. This is a lack of expansion space.Buildings/factories often became out of date. parvenue technologies had been introduced into the industries, and the basic eachy the old factories were unsuited to the modern techniques. Often the buildin gs became derelict, and too unsound to repair. The new factories were bigger and better, and could not expand in the inner city therefore they moved into the suburban areas. As the new companies looked for places to expand into, they angleed to stay off the inner city.The infrastructure was poor. The roads were too small to accommodate all the large vehicles. People living in the inner city tend to park their cars on the side of the road therefore causing a blockage, or narrow roads. As the factories closed and moved, so did the majority of the population. As a result shops and restaurants suffered, and struggle to find business.
