Comparing trends in visits to four different kinds of amenities The aim of this essay is to compare the trend in visits to four different kinds of amenities between the years of 2007 and 2011 in the US. These comparisons include sports complexes, libraries, children's museums and art galleries. The objective is to subsidize governmental and private actions aimed at improving tourism and leisure activities in the country. The first comparison is the number of visitors to the sports complex, which had grown from 5,000 to almost 60,000 in the time period, a near 12 fold growth, with a positive linear trend. It was the most expressive increase, compared to the other places. Secondly, there is the number of library visitors. It was observed that there was an irregular behaviour in it, with a positive growth in the first year, starting with 10,000 and finishing with 50,000 visitors. After that, there were positive and negative changes, ending with 12,000 in 2011. The third place we studied were the children's museums. These had an almost steady behavior in the given time period, with an average of 20,000 visitors per year. Nevertheless, we observed a slight positive trend. The fourth and last place were the art galleries, with a clear descending trend. This place started with 30,000 and finished the period with 11,000 visitors. It's the lowest value in the series. In conclusion, by the end of the study the numbers of visitors at children's museums and at libraries were almost the same, when compared with the beginning of the observation period. In addition, while the number of visitors at sports complexes has been increasing heavily in recent years, there has been a consistent decrease of visitors attending art galleries. The next step is to find the factors influencing these numbers and trends, mainly in order to address the causes of the poor performance in the artistic sector, but also to improve the sectors with already steady numbers.
