Self-Reported Height and Shoe Size Data from Forocoches

self_reports_fc.csv

This repository contains a tabular dataset of 4,739 self-reported height and shoe-size entries collected from public discussion threads on Forocoches between 2010 and 2025.

The dataset has been processed to remove any potentially identifiable or traceable information. All identifiers have been replaced with synthetic numeric IDs, and metadata that could enable reconstruction of original posts has been excluded.

The dataset includes the following fields:

• thread — anonymized thread identifier (numeric ID)
• user — anonymized user identifier (numeric ID)
• height — reported height (cm)
• shoe_size — reported EU shoe size

Height values are expressed in centimetres, and shoe sizes follow the European sizing system. The data reflect self-reported measurements as originally provided by users. No validation, plausibility filtering, or external correction has been applied.

This dataset is intended for population-level statistical analysis of quantitative relationships derived from informal numeric self-disclosure. The anonymization procedure preserves structural relationships in the data while reducing the risk of re-identification.

self_reports_fc_validation.csv

This repository also includes a validation dataset containing 500 entries derived from the original corpus.

The dataset has been processed following the same anonymization procedure as the main dataset. All identifiers have been preserved as in the original dataset to ensure traceability across datasets, and no information enabling the reconstruction of original posts is included.

The dataset includes the following fields:

• thread — anonymized thread identifier (numeric ID)
• user — anonymized user identifier (numeric ID; may be missing, indicating that the user was not included in the dataset)
• height_human — height value manually extracted (cm)
• height_llm — height value extracted by the LLM (cm)
• shoe_human — shoe size manually extracted (EU size)
• shoe_llm — shoe size extracted by the LLM (EU size)
• height_detect_human — indicator (1/0) of whether a height value is present according to manual extraction
• height_detect_llm — indicator (1/0) of whether a height value is detected by the LLM
• shoe_detect_human — indicator (1/0) of whether a shoe size value is present according to manual extraction
• shoe_detect_llm — indicator (1/0) of whether a shoe size value is detected by the LLM
• height_error_abs — absolute difference between height_human and hei
