About this Dataset

Olympic Historical Dataset From Olympedia.org

Context

This dataset is as an attempt to create up to date Olympic Event datasets (from 1986 to 2022 Olympics Game) for any sports/data enthusiast to use to visualise and create some insights on the Olympic Event dataset.

Unique Feature of the Dataset

This dataset contains ranking of each sporting event linked to speicfic country / athlete, which could be used to for any performance related analytics
This dataset contains string information about the athlete's Bio, which could be useful in understanding more about the athlete

Basic Dataset Information

This dataset contains:

154,902 unique athletes and their biological information i.e. height, weight, date of birth
All Winter / Summer Olympic games from 1896 to 2022
7326 unique results (result for a specific event played at an Olympic game)
314,726 rows of athlete to result data which includes both team sports and individual sports
- each row includes position - which is how well the athlete performed for the specific event (Ranked)
  - Note: not all position is integer - contains strings which contains information on which round / heat they achieved
235 distinct countries (some existing from the past)

How to Use the Dataset for a complete athlete-event dataset

Olympic_Athlete_Event_Results.csv - Contains basic athlete to result data (including athlete_id and result_id)
LEFT JOIN Olympic_Athlete_Event_Results.csv file with Olympic_Athlete_Bio.csv (on athlete_id) for complete information of the athlete (i.e. height, weight, date of birth when participating in the event)
LEFT JOIN Olympic_Athlete_Event_Results.csv with Olympic_Results.csv (on result_id) to obtain detailed information about the result (i.e. start date, sport, result_participants, format, time
Aggregate information to obtain features such as:
- BMI - from height and weight
- Age of participation - start date of the result subtract the date of birth of the athlete
TODO: Create a Kernal to demonstrate how above step works

Where the Data is Obtained

The data is scrapped from www.olympedia.org which has the latest up to date olympic data set from 1896 Athene Summer Olympics to Beijing 2022 Winter Olympics. Web Scrapping Project is provided via the source code in github using Python's BeautifulSoup.

Entity Relationship Table - Schema

Note: Credit to @Richnou for providing the data schema for the dataset!

Data Validation

Athlete to event data is validated by providing some data aggregation to medal tally data and then compared the counts of medals won by each country in all Winter / Summer Olympic games. Details are provided via source code in github
