| # Dataset Card for Global Height and Scale Comparison Dataset |
|
|
| A comprehensive dataset of height information covering humans, fictional characters, animals, plants, and objects across multiple scales — from microscopic to astronomical. |
|
|
| This dataset provides a unified resource for developers, researchers, and educators interested in visualizing and analyzing height and scale relationships across diverse categories. |
|

|
| ## Dataset Details |
|
|
| ### Dataset Description |
|
|
| The **Global Height and Scale Comparison Dataset** compiles verified and estimated height data across multiple domains: |
|
|
| - **Humans:** Average male/female heights by country, age group (children, adults, elderly), and global anthropometric references. |
| - **Celebrities:** Includes verified heights of actors, athletes, politicians, historical figures, and record holders. |
| - **Fictional Characters:** Heights from popular anime (e.g., *One Piece*, *Attack on Titan*, *Naruto*), films (*Star Wars*, *The Walking Dead*), and games. |
| - **Animals & Plants:** Average sizes of various species, from domestic pets to wild animals and notable plants. |
| - **Objects & Celestial Bodies:** Relative scales of real-world and cosmic objects — from atoms and DNA molecules to mountains, planets, and stars. |
|
|
| This dataset was curated to support visualization, educational, and creative applications related to **human and object scale comparison**. |
|
|
| - **Curated by:** Independent Research Initiative |
| - **Language(s):** Multilingual numeric data |
| - **License:** Apache 2.0 |
|
|
| ### Dataset Sources |
|
|
| - **Primary Sources:** Public anthropometric datasets, scientific databases, verified entertainment sources, and educational references. |
| - **Supplementary Sources:** Community-contributed data and cross-referenced measurements from reputable online databases. |
| - **Demo Visualization:** [https://compareheights.org](https://compareheights.org) |

|
| ## Dataset Creation |
|
|
| ### Curation Rationale |
|
|
| The dataset was created to provide a **standardized reference for comparing scale and proportion** across humans, fictional characters, and physical objects. |
| It enables seamless integration into visualization tools, simulations, and educational applications. |
|
|
| A visualization tool that inspired and demonstrates the value of this dataset is [**Height Comparison**](https://compareheights.org), which turns numeric height data into intuitive, visual charts for exploration and learning. |
|
|
| ### Source Data |
|
|
| #### Data Collection and Processing |
|
|
| - Collected from verified anthropometric studies, entertainment databases, and academic resources. |
| - Normalized into metric and imperial units for interoperability. |
| - Cross-checked for consistency and duplicates removed. |
|
|
| #### Who are the source data producers? |
|
|
| Data was derived from open data repositories, academic research, and publicly available references (e.g., IMDb, sports databases, anime wikis, and NASA records). |
|
|

|
|
| ## Bias, Risks, and Limitations |
|
|
| - Height data for fictional characters may be based on estimated or fan-sourced information. |
| - Some animal or planetary data are averaged or rounded from scientific references. |
| - Users should not treat this dataset as medically or anthropometrically authoritative. |
| - The dataset focuses on comparative visualization rather than statistical precision. |
|
|
| ### Recommendations |
|
|
| Use this dataset for **relative and educational comparisons**, not for critical biometric or physiological analyses. |
