Quickstart

import pandas as pd

# Stream straight from the Hub — no download step needed
df = pd.read_csv("hf://datasets/datamatastudios/skill-demand-index/skill-demand-index.csv")

# Highest-demand skills right now
print(df.sort_values("demand_pct", ascending=False).head(10))

Or load it with the 🤗 datasets library:

from datasets import load_dataset

ds = load_dataset("datamatastudios/skill-demand-index")

What you can answer with it

• Which skills lead demand in data, engineering, product, DevOps, security or AI — and by how much.
• How often a skill is a hard requirement versus nice-to-have (required_count vs listing_count).
• How a skill's demand share moves over time, by appending each daily snapshot.

Columns

Column	Type	Description
snapshot_date	string	UTC date the snapshot was computed (YYYY-MM-DD).
category	string	Role category: data, engineering, product, devops, security or ai.
skill	string	Normalised skill name.
skill_group	string	Skill family the skill belongs to (e.g. language, cloud, framework).
listing_count	number	Active listings in the category that mention the skill.
total_listings	number	Total active listings in the category on that date.
demand_pct	number	listing_count / total_listings x 100, rounded to 0.1.
required_count	number	Listings where the skill is a hard requirement (vs nice-to-have). Blank for rows snapshotted before this was tracked.

How it is built

Active tech job listings are scraped daily from public applicant-tracking systems (Greenhouse, Lever, Ashby) and aggregated boards. For each role category the demand share of a skill is listings_with_skill / total_active_listings x 100. This release is the most recent daily snapshot for all six categories.
