+
+[Folktexts](https://github.com/socialfoundations/folktexts) is a suite of Q&A
+datasets with natural outcome uncertainty, aimed at evaluating LLMs' calibration
+on unrealizable tasks.
+
+The *folktexts* datasets are derived from US Census data products.
+Namely, the datasets made available here are derived from the
+[2018 Public Use Microdata Sample](https://www.census.gov/programs-surveys/acs/microdata/documentation/2018.html)
+(PUMS). Individual features are mapped to natural text using the respective
+[codebook](https://www2.census.gov/programs-surveys/acs/tech_docs/pums/data_dict/PUMS_Data_Dictionary_2018.pdf).
+Each task relates to predicting different individual
+characteristics (e.g., income, employment) from a set of demographic features
+(e.g., age, race, education, occupation).
+
+Importantly, every task has natural outcome uncertainty. That is, in general,
+the features describing each row do not uniquely determine the task's label.
+For calibrated models to perform well on this task, the model must correctly
+output nuanced scores between 0 and 1, instead of simply outputting discrete
+labels 0 or 1.
+
+Namely, we make available the following tasks in natural language Q&A format:
+- `ACSIncome`: Predict whether a working adult earns above $50,000 yearly.
+- `ACSEmployment`: Predict whether an adult is an employed civilian.
+- `ACSPublicCoverage`: Predict individual public health insurance coverage.
+- `ACSMobility`: Predict whether an individual changed address within the last year.
+- `ACSTravelTime`: Predict whether an employed adult has a work commute time longer than 20 minutes.
+
+
+These tasks follow the same naming and feature/target columns as the
+[folktables](https://github.com/socialfoundations/folktables)
+tabular datasets proposed by
+[Ding et al. (2021)](https://proceedings.neurips.cc/paper_files/paper/2021/file/32e54441e6382a7fbacbbbaf3c450059-Paper.pdf).
+The folktables tabular datasets have seen prevalent use in the algorithmic
+fairness and distribution shift communities. We make available natural language
+Q&A versions of these tasks.
+
+The datasets are made available in standard multiple-choice Q&A format (columns
+`question`, `choices`, `answer`, `answer_key`, and `choice_question_prompt`), as
+well as in numeric Q&A format (columns `numeric_question`,
+`numeric_question_prompt`, and `label`).
+The numeric prompting (also known as *verbalized prompting*) is known to improve
+calibration of zero-shot LLM risk scores
+[[Tian et al., EMNLP 2023](https://openreview.net/forum?id=g3faCfrwm7);
+[Cruz et al., NeurIPS 2024](https://arxiv.org/pdf/2407.14614)].
+
+**The accompanying [`folktexts` python package](https://github.com/socialfoundations/folktexts)
+eases customization, evaluation, and benchmarking with these datasets.**

+## Dataset Details
+
+### Dataset Description
+
+- **Language(s) (NLP):** English
+- **License:** Code is licensed under the MIT license; Data license is governed by the U.S. Census Bureau [terms of service](https://www.census.gov/data/developers/about/terms-of-service.html).
+
+### Dataset Sources
+
+- **Repository:** https://github.com/socialfoundations/folktexts
+- **Paper:** https://openreview.net/forum?id=qrZxL3Bto9
+- **Data source:** [2018 American Community Survey Public Use Microdata Sample](https://www.census.gov/programs-surveys/acs/microdata/documentation/2018.html)
+
+## Uses
+
+The datasets were originally used to evaluate LLMs' ability to produce
+calibrated and accurate risk scores in the [Cruz et al. (2024)](https://arxiv.org/pdf/2407.14614) paper.
+
+Other potential uses include evaluating the fairness of LLMs' decisions,
+as individual rows feature protected demographic attributes such as `sex` and
+`race`.

+**TODO!**
+
+## Dataset Creation
+
+### Source Data
+
+The datasets are based on publicly available data from the American Community
+Survey (ACS) Public Use Microdata Sample (PUMS), namely the
+[2018 ACS 1-year PUMS files](https://www.census.gov/programs-surveys/acs/microdata/documentation.2018.html#list-tab-1370939201).
+
+#### Data Collection and Processing
+
+The categorical values were mapped to meaningful natural language
+representations using the `folktexts` package, which in turn uses the official
+[ACS PUMS codebook](https://www2.census.gov/programs-surveys/acs/tech_docs/pums/data_dict/PUMS_Data_Dictionary_2018.pdf).
+The data download and processing was aided by the `folktables` python package,
+which in turn uses the official US Census web API.
+
+#### Who are the source data producers?
+
+U.S. Census Bureau.
