Research guide

Research landscape

Chicago has long been a major advertising and marketing centre, and today it hosts full-service agencies, qualitative specialists, B2B and healthcare firms, data collection centres and focus group facilities. It is also the main base for research covering the Midwest.

Be clear about the area you mean: the city has about 2.73 million people, but the Chicago-Naperville-Elgin metro area (“Chicagoland”) has 9.43 million and extends into Indiana. The city is less than a third of the metro area, and suburban residents are older and less likely to speak another language at home, so city-only and metro-wide samples give different results.

Who you will interview

Chicago is younger than its suburbs (median age 35.9 in the city, 38.9 in the metro area) and very mixed: about 29.7% of residents are Hispanic or Latino, 27.9% Black, 32.1% White non-Hispanic and 7.3% Asian. 22% were born outside the United States and 35.4% of residents aged five and over speak a language other than English at home.

Spanish is the most common, followed by languages such as Mandarin, Polish, Arabic, Hindi and Urdu, and 368,073 residents speak English less than “very well”. For studies that must reflect the whole city, set quotas on Hispanic origin, race and age using Chicago figures, not national ones, and plan a Spanish questionnaire and bilingual interviewers or moderators.

Fieldwork in practice

The city is divided into 77 community areas, whose boundaries do not change over time, and 50 wards. Community areas are the usual unit for sampling and quotas; neighbourhood names are widely used but have no official boundaries.

Residential segregation is strong: 27 of the 77 community areas are predominantly Black, mostly on the South and West Sides. A sample drawn from a few areas can therefore be badly skewed by race and income: spread interviews across community areas, or stratify by them. Online is the main method for consumer surveys (89.1% of households have a broadband subscription), with telephone or in-person interviews for offline or older audiences. Only 46.0% of homes are owner-occupied and 13.6% of residents moved in the previous year, so address-based and door-to-door studies need more contact attempts.

Focus groups and qualitative research

In-person groups are usually held in dedicated viewing facilities downtown or in the suburbs, with a one-way mirror and video streaming. Choose the location according to the target: a downtown facility for city residents, a suburban one for metro-wide or family targets.

Illinois has a strict biometric law, the Biometric Information Privacy Act (BIPA). Photographs are not biometric identifiers, but a scan of face geometry is: if a study uses facial coding, emotion analysis or face recognition on video, the agency must first inform participants in writing of the purpose and duration, obtain a written release, publish a retention policy and destroy the data once the purpose is met, and within 3 years of the last interaction at most. Damages are $1,000 per negligent and $5,000 per intentional or reckless violation, so check this before any video analysis tool is used.

Timing

Winters are harsh: the average January temperature is 25.2°F (−3.8°C) and the city gets about 38.4 inches of snow a year, mostly from December to February. Snowstorms can cancel in-person groups and slow door-to-door fieldwork, so allow spare days and offer online sessions as a fallback in winter.

Avoid Thanksgiving, the Christmas and New Year period and the summer holiday season for B2B targets, as in the rest of the country, and check the Chicago Public Schools calendar for studies with parents or children.

Working with a Chicago agency

• Share a clear brief: objectives, target, sample size, city or metro area, community areas, method, languages (English, Spanish) and deadline.
• Ask how the agency spreads interviews across community areas and reaches Hispanic and Black residents, renters and offline groups.
• For focus groups, ask for the facility address (downtown or suburbs), viewing room capacity, streaming options and incentive levels.
• If video will be analysed with facial coding or similar tools, ask how the agency obtains BIPA written consent and when it destroys the data.
• Plan winter fieldwork with spare days and an online fallback.
• Compare several proposals: you can send one request to up to 5 Chicago companies from this page.
