# Identity Biases in Diffusion Models: Professions
        
Explore profession-level social biases in the data from [DiffusionBiasExplorer](https://hf.co/spaces/society-ethics/DiffusionBiasExplorer)!
This demo leverages the gender and ethnicity representation clusters described in the [companion app](https://hf.co/spaces/society-ethics/DiffusionFaceClustering)
to analyze social trends in machine-generated visual representations of professions.
The **Professions Overview** tab lets you compare the distribution over
[identity clusters](https://hf.co/spaces/society-ethics/DiffusionFaceClustering "Identity clusters identify visual features in the systems' output space correlated with variation of gender and ethnicity in input prompts.")
across professions for Stable Diffusion and Dalle-2 systems (or aggregated for `All Models`).
The **Professions Focus** tab provides more details for each of the individual professions, including direct system comparisons and examples of profession images for each cluster.
This work was done in the scope of the [Stable Bias Project](https://hf.co/spaces/society-ethics/StableBias).
As you use this demo, please share findings and comments [in the discussions tab](https://hf.co/spaces/society-ethics/DiffusionClustering/discussions)!
"""

_ = """
 For example, you can use this tool to investigate:
 - How do each model's representation of professions correlate with the gender ratios reported by the [U.S. Bureau of Labor
Statistics](https://www.bls.gov/cps/cpsaat11.htm "The reported percentage of women in each profession in the US is indicated in the `Labor Women` column in the Professions Overview tab.")?
Are social trends reflected, are they exaggerated?
- Which professions have the starkest differences in how different models represent them?
