DisImpact: Disaster Physi-Social Impact Classification

Dataset Description

Dataset of the paper "DisImpact: Quantifying the Physi-Social Impact of Natural Disasters Through Social Media ". This dataset contains post IDs and disaster impact labels for hurricane and wildfire across three platforms: Reddit, TikTok, and YouTube.

Data Format

Each disaster–platform subset is stored in a CSV file named <disaster>_<platform>_social.csv, with two columns:

Column	Type	Description
id	string	id of the post.
label	integer	Disaster impact category, numbered from 1 to 11.

Always read id as a string. Numeric conversion can alter identifiers, especially long TikTok IDs. CSV files do not preserve column types.

Label Definitions

Labels 1–10 follow the category order in Table 3 of the paper. Descriptions below are abbreviated.

Label	Domain	Category	Description
1	Physical	Casualties & Injuries (CINJ)	Deaths, injuries, missing people or animals, and immediate medical emergencies.
2	Physical	Evacuations & Displacement (EVAC)	Forced evacuation, displacement, or relocation to shelters.
3	Physical	Infrastructure & Utility Damage (INFR)	Damaged infrastructure or disrupted utilities.
4	Physical	Environmental Damage (ENVD)	Ecosystem damage, agricultural losses, or environmental contamination.
5	Physical	Resource Shortages (RSRC)	Requests for essential survival supplies.
6	Social	Public Health (PUBH)	Disease outbreaks, interrupted healthcare, or medical supply shortages.
7	Social	Emotional & Psychological Distress (EMOT)	Disaster-related trauma, anxiety, grief, or other emotional suffering.
8	Social	Bias Narratives (BIAS)	Discrimination, political blame, or unequal impacts across groups.
9	Social	Assistance & Recovery (ASST)	Aid, rebuilding, community support, and adaptation.
10	Social	Socioeconomic Disruption (SECO)	Disruption to livelihoods, housing, education, or economic activity.
11	Other	None of the Above (OTHER)	None of categories 1–10 applies.

Label 11 does not necessarily mean that a post is unrelated to the disaster.

Privacy and Content Access

To protect user privacy, only post IDs are released. We recommend retrieving the full post content via the official APIs of each platform, in accordance with their respective terms of service.

• Reddit API
• TikTok API
• YouTube API

The released CSV files contain post IDs and classification labels; they do not include post text, images, videos, or user profiles. Content availability may change if posts are deleted, made private, or otherwise become inaccessible.

Limitations

Labels are model-generated annotations and may contain errors. Each post receives a single category, even when it describes multiple impacts. Social media observations should not be interpreted as a representative measure of all affected populations or as verified disaster incident reports.
