Today we continue where we left off last week. We ended up talking about the tourist boom that started between 1950-1973 and the growth that this meant for the sector. This increase was due to  international order, social stability, greater purchasing power, etc. In this decade, paid vacations, the 5-day working week, the 40-hour working week, and the extension of social care that favour leisure and tourism were introduced. The economic recovery of countries such as Germany or Japan was surprising in terms of the salient levels of income that gave rise to the well-off middle During those years the big cities grew, leading to overcrowding and stress and creating  the need for escape,  and the desire to clear the mind of pressure. In addition, the construction of new roads and highways allowed a greater flow of travellers. A big mistake in the sector was the non-planning of demand, which caused a large number of constructions to be produced without measuring the impacts that this would have on both environmental and social levels. A large number of identical tour packages began to be launched onto the market by large tour operators meaning that a greater number of tourists could afford the option to travel. In 1950 there were 25 million tourists, in 1973 the figure reached 200 million and currently there are 1,322 million. The energy crisis of 1973 significantly affected tourism, causing the closure of tourist establishments and the fall in the number of tourists. The recession provoked a decline in quality with the intention of attracting tourists and thus maintain income. This caused the massification of supply and demand in the case of tourism. In the 80s, the standard of living grew again and tourism became the economic engine of many countries, especially in Western countries. This was partly due to the improvement in transportation, new and better aircraft, high-speed trains, the consolidation of charter flights, etc. The tourist offer grew thanks mostly to the increase of tourist apartments. 1989, fall of the Berlin Wall. The fall of the wall causes the beginning of a new world of destinations to which to travel. This, added to the increased competition between the airlines favours the cheapening of the international flights that generates a new growth, this time more moderate, of  tourism. It is at this time when measures begin to be imposed to control the growth of this sector with measures such as adjusting supply to meet demand, imposing limits of capacity at monuments, among others. In addition, in the 90s, both supply and demand began to diversify. In the case of supply, new types of products and destinations appear and, on the demand side, new types of tourists appear. On the other hand  quality begins to be an important point in tourism with tourists prefering to spend more if the quality they will receive is higher. With the passage of time, tourism has evolved and there is great diversity in demand such as individual, massive, cultural, natural, active, business, scientific, space, nuclear, sexual and hunting tourism. Currently, tourism is one of the most important economic activities on which a country can count, becoming one of the largest sources of income as well as being a generator of employment for these states. That is why the countries that depend on tourism must have both supply and demand controlled to avoid overcrowding. I hope you liked it and we can enjoy tourism for a long time.
