across <strong>in</strong>stitutions, whether for structural or adm<strong>in</strong>istrative reasons. For example, <strong>in</strong><strong>in</strong>stitutions present<strong>in</strong>g the perform<strong>in</strong>g arts, buy<strong>in</strong>g a ticket is the most basic level ofparticipation; <strong>in</strong> museums, it is a museum visit. In both types of <strong>in</strong>stitutions, higher levelsof participation may be <strong>in</strong>dicated by season-ticket hold<strong>in</strong>g, or some form of membership.The basic unit <strong>in</strong> the analysis is geographical, not <strong>in</strong>dividual.Us<strong>in</strong>g databases of census tracts and street addresses, the National Op<strong>in</strong>ion Research<strong>Center</strong> (NORC) at the University of <strong>Chicago</strong> geocoded all addresses <strong>in</strong> our data set; thelocation of each address <strong>in</strong> our files was identified, and the address was mapped onto theappropriate street segment. This analysis makes it possible to produce maps show<strong>in</strong>g thedistribution of activity across the entire <strong>Chicago</strong> MSA and beyond.Furthermore, it makes l<strong>in</strong>kage possible between our records of participation <strong>in</strong> cultural<strong>in</strong>stitutions and data about the community available elsewhere. Our primary source ofexternal data is the 2000 Census, which provides <strong>in</strong>formation, also based on censustracts, on socioeconomic characteristics such as <strong>in</strong>come, education, and householdcomposition, as well as crucial data on race and ethnicity.Though we can l<strong>in</strong>k household addresses <strong>in</strong> the database to specific areas, we need totake <strong>in</strong>to account the size of the population <strong>in</strong> each location to be able to compare andcontrast areas. We choose density of participation as our first measure, where density ismeasured as the proportion of households <strong>in</strong> an area that participate <strong>in</strong> at least one ofthese <strong>in</strong>stitutions. In calculat<strong>in</strong>g levels of participation we use population basel<strong>in</strong>e datafrom the 2000 Census; changes <strong>in</strong> population size and composition s<strong>in</strong>ce 2000 are notreflected <strong>in</strong> our measures. 4From census figures, we know the characteristics of the areas where people live,but we do not know the characteristics of the <strong>in</strong>dividuals or hous<strong>in</strong>g units <strong>in</strong> ourown database.Individual names and identification are removed from the records before we analyzethem, and we have no access to personal characteristics of <strong>in</strong>dividuals or families.A household can appear multiple times <strong>in</strong> the overall database, either because it hasmultiple transactions with a particular organization, or because it has transactions withmany organizations, or both. We measure participation as a household’s <strong>in</strong>volvement withat least one organization. In select<strong>in</strong>g the data po<strong>in</strong>ts for each map, a household isrepresented only once. 54 Look<strong>in</strong>g to the future, the U.S. CensusBureau’s new large-scale national survey,the American Community Survey (ACS),will provide updated <strong>in</strong>formation aboutpopulation size and composition on aroll<strong>in</strong>g basis from 2008 onward.5 A shortcom<strong>in</strong>g of the data is that schoolgroups and other social or civic groups areexcluded. In no case, however, were thosedata available at the level of the <strong>in</strong>dividualparticipant; <strong>in</strong>deed, <strong>in</strong>stitutional recordsof such visits were often not even <strong>in</strong>electronic form.21
