Why we built this

Choosing a career is a big decision, but most advice online is based on opinions, trends, or vague claims. At the same time, the U.S. government publishes decades of real job market data that most people never look at because it’s hard to understand. We wanted to take that real data and turn it into something visual, interactive, and actually useful.

What it does

You pick a job. The website shows how that career has changed over time, compares across states, how risky it is to automation, and what current trends suggest for the future. Everything you see is based on real historical data, not scraped job postings or generated numbers.

The data

All the numbers in Vocation Tangent come from official U.S. labor datasets, mainly:

Bureau of Labor Statistics (Occupational Employment Statistics)
O*NET job and work context data
Salaries are reported wages, not estimates from job ads
Demand is based on actual employment numbers
Trends are consistent and comparable across many years

Gemini AI is only used to analyze and explain this data,it does not replace it.
