# 🧠 data_jobs Dataset |
|
|
|
|
|
A dataset of real-world data analytics job postings from 2023, collected and processed by Luke Barousse. |

|
|
|
## Background |
|
|
|
|
|
I've been collecting data on data job postings since 2022. I've been using a bot to scrape the data from Google, which come from a variety of sources. |
|
|
|
|
|
You can find the full dataset at my app [datanerd.tech](https://datanerd.tech). |
