O'Hare

O'Hare, located on the far northwest side of Chicago, Illinois, is one of the city's 77 official community areas. O'Hare International Airport is located within the boundaries of this community area. This community area is the only one that extends outside Cook County; the western edge (an area comprising the southwest part of the airport) is in DuPage County. The area is a transportation hub containing O'Hare International Airport as well as major roads such as Interstate 90, its auxiliary Interstate 190, Interstate 294, Illinois Route 72, Illinois Route 171, U.S. Route 12 and U.S. Route 45. This allows the O'Hare neighborhood, combined with the nearby suburb of Rosemont, to work as an edge city. (Source: Wikipedia)

Housing market indicators

All of these property level data sets are connected to parcel-level data files from the county Assessors offices that include data on every parcel in the Chicago metropolitan area. All of these parcel-level data sets include historical data and are updated on a regular basis ranging from every week to every year depending on the data set.

Housing Stock Composition

Data on the housing stock provides context about the underlying characteristics of a neighborhood’s housing market and helps in the interpretation of patterns and trends in property sales, mortgage lending activity, foreclosure filings, and completed auctions activity. Understanding an area's housing stock can help determine the appropriate targeted strategies for stabilizing local housing markets, preserving and creating affordable rental housing, and promoting neighborhood investment.
