Investigating the value of urban living 2010
Report summary
1.Background and purpose of study
The purpose of this study is to determine the types of value urban residents see in relation to what aspects of their town or where in town they live. In terms of the value of towns, many books with rankings of towns people want to live in have been published, but the indices serving as the basis for calculations are often economic indices, such as land price and rent, or indices that quantitatively evaluate the environment in terms of equipment and facilities, such as the number of facilities per unit of population or gross floor area of households. Needless to say, although these indices are useful for calculating rankings because they allow for quantitative comparisons, environments that residents find attractive are not limited to size or economic evaluations, and considerations of whether they can live comfortably (that is, the quality of town) are important.
While keeping in mind these issues, this study aims to: individually interview urban residents using an “Evaluation Grid Method” to ask about where in their towns they like or consider good, and why; clarify the structure of evaluations of areas based on the opinions of residents; and propose physical environments or factors that should be provided to create towns that make residents want to stay.

3. Study method
In this study, we conducted a survey of individual interviews based on the “Evaluation Grid Method” as a method for structurally understanding the “true needs” that individual urban residents seek for areas and locations by associating these needs with specific locations and elements. The “Evaluation Grid Method” is an interview method that has been improved and developed based on interview methods developed in the field of clinical psychology and is widely used to understand a variety of needs (requests) associated with environment, etc. The premise of this method is the “Personal Construct Theory”, which posits that human beings “each have a unique ‘cognitive structure’, which is a mechanism of understanding and judgment, and they try to understand external information obtained through sight, sound, and other senses by processing information with this mechanism to determine the actions they should take and predict outcomes.” The “cognitive structure” in this case is a “hierarchical structure” having specific understandings such as “a spacious or non-spacious skyline” at the bottom, sensory understandings such as “feels or does not feel liberating” in the middle, and more abstract value judgments such as “able to unable to relax” at the top. The Evaluation Grid Method can be described as a method aiming to selectively pick up only certain aspects (i.e., the “evaluation structure”) related to the surveyed “evaluation” within the individual cognitive structure.
In general procedures of the evaluation grid method, respondents are first asked to think about multiple subjects to determine “which one they like”, and are then asked for the reasons for their judgment criteria. In this study, however, we set the subjects that the respondents were asked to evaluate as “locations within their residential areas that they consider good and like” and asked for reasons such as “why they like it” and “why they consider it good” for each location determined as being “liked” and “good”. This was because we wanted to have the respondents pick several “locations that they consider good and like” and it was awkward to have the respondents rank these locations. In addition, we also asked whether the locations were used in their daily lives, whether they served as destinations, and whether they were one of the reasons why they liked their towns.
Assuming that evaluation structures vary between residential areas, we picked the Sangen-Jaya area in Setagaya ward (a location where commercial and residential areas, as well as new buildings and traditional downtown shopping districts coexist, and there is a mixture of both old and new houses and various shop sizes) and the Konan area in Minato ward (a new town where large-scale redevelopment is taking place; the number of high-rise apartments has recently been increasing and many residents are new to the area) as our surveyed areas that we believed to have different characteristics. In addition, taking differences in life stages into consideration, we included various generations, including seniors and nurturers, among the respondents.
We conducted surveys in the Konan areas in July and September of 2009 and in the Sangen-Jaya area in September and October. The interview survey was conducted by one interviewer and one note-taker, and we spent about one hour for each respondent.
