Public places allow people to communicate as they like, because it is possible for everyone to be involved, including families, social and cultural groups, friends, neighbors, colleagues, etc. the more convenient and better the relationships of the groups and the different strata, the social relations are more difficult. However, in this study, different groups are reluctant to communicate with each other, and the separation between them is obvious and tangible. This study investigates the different public places in urban areas over a year, a case study of the city of Ayeslbury in the south - east of England with an estimated population of 69000. The purpose of this research is to find out how different people use public spaces and how interactions vary according to age and gender and location. The findings with respect to the policy of public spaces of regions are considered. The method of research is a combination of qualitative and quantitative research, which includes interviews of horsemen, managers and urban planners, business owners and shops, and passersby in these places. The study was carried out by 46 (16 - 73 years) over 12 months (from October 2004 to September 2005). Observations in general were made in 3 places, residential areas, green spaces, city centers, from 7 am to 1 in the night. In this study, we evaluate the accuracy of the social and demographic characteristics that observers have identified. Rather, the interpretation of observers is one of the ways determined by the groups assigned to it. As a result, the language and label that are used for each group will be used in this document. The study also analyses whether the interactions are different from the age or with the location. Or does the presence of people or special groups influence the use of public space.
