Chicago Face Database

T H E15spaceD A T A B A S E

The Chicago Face Database was developed at the University of Chicago by Debbie S. Ma, Joshua Correll, and Bernd Wittenbrink. The CFD is intended for use in scientific research. It provides high-resolution, standardized photographs of male and female faces of varying ethnicity between the ages of 17-65. Extensive norming data are available for each individual model. These data include both physical attributes (e.g., face size) as well as subjective ratings by independent judges (e.g., attractiveness).

Detailed information about the construction of the database and the available norming data can be found in Ma, Correll, & Wittenbrink (2015).

The database consists of a main image set and several extension sets. Images are standardized across all sets so that they can be used side-by-side.

CFD

The main CFD set consists of images of 597 unique individuals. They include self-identified Asian, Black, Latino, and White female and male models, recruited in the United States. All models are represented with neutral facial expressions. A subset of the models is also available with happy (open mouth), happy (closed mouth), angry, and fearful expressions. Norming data are available for all neutral expression images. Subjective rating norms are based on a U.S. rater sample.

CFD-MR

The CFD-MR extension set includes images of 88 unique individuals, who self-reported multiracial ancestry. All models were recruited in the United States. The images depict models with neutral facial expressions. Additional facial expression images with happy (open mouth), happy (closed mouth), angry, and fearful expressions are in production and will become available with a future update of the database. Norming data include the standard set of CFD objective and subjective image norms as well as the models’ self-reported ancestry. Subjective norms are based on a U.S. rater sample.

CFD-INDIA

The CFD-INDIA extension set includes images of 142 unique individuals, recruited in Delhi, India. The images depict models with neutral facial expressions. Additional facial expression images with happy (open mouth), happy (closed mouth), angry, and fearful expressionsare in production and will become available with a future update of the database. Norming data consist of the standard set of CFD objective and subjective image norms, including ratings of perceived ethnicity. Subjective norms are available for a U.S. rater sample and for a sample of raters recruited in India. In addition, an extended set of self-reported model background data (e.g., ancestry, home state, caste) is available upon request.

Resources meant to facilitate the use of the Chicago Face Database.

Several labs have developed materials related to the Chicago Face Database. We have begun to make a selection of them available under the Resources tab. They currently include tools for image modification (e.g., landmark templates for image morphing) and modified image sets (e.g., facial expression morphs). If you would like to add your own resources to this space, please contact us at cfd@chciagobooth.edu

Terms of Use
We have updated our Terms of Use, clarifying that CFD materials cannot be shared via file hosting services. Likewise, the release of CFD materials to cloud-based services (e.g., for the purpose of AI image manipulation) violates the Terms of Use.

Acknowledgement
Development of the Chicago Face Database would not have been possible without the dedicated and generous support from many. A list of our supporters can be found here.

March 2021
Version 3.0
Release of the CFD-INDIA Expansion Set and Maintenance Update
Publication of face images for 142 unique individuals, recruited in Delhi, India, with norming data.
Correction of errors in the Facial Width-to-Height Ratio measure. Specifically, this measure has been updated for all database images and is now based on the ratio of the bizygomatic face-width measure and the distance between the upper lip and highest point of the eyelids. The resulting ratio is identified as fWHR2. The fWHR1 measure used in prior versions of the database relied on a less common definition of the ratio (Hehman et. al. 2013). It remains available here for the main CFD image set. However, use of the fWHR1measure is discouraged as it contains unreliable height measurements.

November 2020
Version 2.5
Addition of CFD-MR Expansion Set
Publication of face images for 88 self-reported multiracial individuals, with norming data. Updated measurement guide.

July 2016
Version 2.0.3
Minor Maintenance Update
This update eliminates several duplicate files from the distributed zip archive. Norming data remain unchanged.

March 2016
Version 2.0.2
Update to Norming Data
This update fixes a typo in the norming data for variable fWHR of target CFD-LM-200. In addition, the codebook now includes scale information for all subjective rating measures. All images included in version 2.0 remain unchanged.

March 2016
Version 2.0.1
Update to Norming Data
This update provides a minor correction to the norming data.
The AGE variable (rater estimates for target’s approximate age in years) now excludes all rater responses over 70. Elimination of outliers for this variable changes the resulting average estimated age for 3 targets:
CFD-AM-215, CFD-BF-041, CFD-BM-216. All images incldued in version 2.0 remain unchanged.

August 2015
Version 2 Published

December 2014
Supplementary Materials to
Ma et al. (2015)
Additional analyses
