Can you explain how to answer this long answer question: 'describe the process of gentrification and its effects?'

Start by providing a clear definition of the process, e.g. Gentrification is where deteriorated urban neighbourhoods are renovated and revitalised by the influx of more affluent residents. Describe what the process involves. Try and include an example(s) to demonstrate a greater understanding, e.g.For example, in London since the 1980s it has become increasingly popular to buy and renovate houses in traditionally less affluent areas of the city. Typically, the first individuals to buy into these areas are those from creative industries such as artists. In turn, such areas start to develop a reputation for being cool, stylish and on the up which often attracts more affluent, middle-class buyers. The increased demand is noticed by estate agents who start to suggest higher asking prices to those selling their property. As more middle-class home owners move into these areas, new independent businesses often begin to emerge. These typically include: coffee houses, bread shops and wine bars. Notable contemporary examples of this process in London are Brixton, Hoxton and Shoreditch. Describe both the positive and negative effects of the process, e.g. The gentrification process can have several benefits and costs. In terms of benefits, urban areas can become renovated, refurbished and improved at little cost to the local authorities. Furthermore, the increase in affluent residents can revive declining communities by increasing custom for local businesses, retailers and libraries. However, gentrification can also have many negative consequences. For example, as an area becomes more expensive, private landlords will increase rent prices. This might drive less affluent tenants out of the areas around which their lives are based. A major consequence of such events is increasing social division and friction as existing communities feel powerless to influence such changes. Provide a clear conclusion that sums up the main points and links the answer back to the question, e.g. To conclude while gentrification might improve the economic and environmental conditions of many once declining urban areas, it typically leads to the displacement of one social group (less affluent) for another (more affluent). Thus, there is much discussion concerning whether gentrification actually improves urban areas, or merely causes deprivation to forcefully migrate elsewhere.
