The dataset generation failed because of a cast error
Error code:   DatasetGenerationCastError
Exception:    DatasetGenerationCastError
Message:      An error occurred while generating the dataset

All the data files must have the same columns, but at some point there are 1 new columns ({'quarter'}) and 2 missing columns ({'year', 'age_group'}).

This happened while the csv dataset builder was generating data using

hf://datasets/who-is-tyler-durden/thailand-road-traffic-injury-aggregates-2018/bkk_quarter_2018.csv (at revision a09de275103bdbbe36b626bdcf1208bfbc00bc5c)

Please either edit the data files to have matching columns, or separate them into different configurations (see docs at https://hf.co/docs/hub/datasets-manual-configuration#multiple-configurations)

Thailand Road-Traffic Injury Aggregates (2018)

Canonical dataset page (EN/TH): https://bangkokfamilylawyer.com/datasets-injury-th/
DOI (this version): https://doi.org/10.5281/zenodo.17538573
Concept DOI (latest): https://doi.org/10.5281/zenodo.17538574

This repository provides aggregated indicators derived from Thailand’s official Injury Surveillance data (Department of Disease Control, Ministry of Public Health) for calendar year 2018.

All outputs are privacy-preserving aggregates; individual-level records are not included.

Contents

Key CSV files (2018 slice):

  • province_2018.csv — Cases by province.
  • bkk_quarter_2018.csv — Bangkok cases by quarter.
  • age_bins_2018.csv — Cases by age group.
  • sex_2018.csv — Cases by sex.
  • mode_mix_bkk_2018.csv — Mode / road-user mix for Bangkok.
  • top10_provinces_2018.csv — Top 10 provinces by case count.
  • bkk_top_amphoe_2018.csv — Leading Bangkok districts.
  • qa_year_counts_2018.csv — Year-level row counts (QA).
  • qa_coverage_province_2018.csv — Coverage / completeness indicators.
  • qa_summary.json — Human-readable QA summary.

File names may be extended as new QA tables or visualizations are added.

Source Data

Source dataset (not redistributed here):

The original dataset remains under its own terms and conditions. This repository only provides derived aggregates.

Methodology (summary)

  • Filtered to events in 2018.
  • Robust date parsing with support for Thai formats and Buddhist Era → Gregorian conversion.
  • Records with invalid or missing core fields are excluded from aggregates.
  • Aggregations computed by:
    • Province and (for Bangkok) district
    • Quarter (Q1–Q4)
    • Age groups
    • Sex
    • Selected mode / road-user categories
  • Small cells may be combined or omitted to reduce re-identification risk.

How to use

Example (Python):

import pandas as pd
from datasets import load_dataset

ds = load_dataset(
    "appdevbangkok/thailand-road-traffic-injury-aggregates-2018",
    split="train"
)
# or load specific CSVs directly via raw URLs if preferred
