Welcome to



"Hedonometer" is an instrument that measures the happiness of large populations in real time.

The word "hedonometer" comes from the economist Francis Edgeworth that coined the term in the late 1800’s to describe "an ideally perfect instrument, a psychophysical machine, continually registering the height of pleasure experienced by an individual."

Hedonometer is based on people’s online expressions, capitalizing on data-rich social media, and measures how people present themselves to the outside world.

Involved Technologies

The creators used the D3 Javascript data visualization library for visualizing the data, Bootstrap for layout, and Django as a web framework.

Hedonometer.org is deployed on a Linode virtual linux server.
