+# It is not always greener on the other side: Greenery  perception across demographics and personalities in  multiple cities
+Repository for additional data used in the paper [**"It is not always greener on the other side: Greenery perception across demographics and personalities in multiple cities"**](https://arxiv.org/abs/2512.17186).
+This project was developed at the Future Cities Lab Global in the Singapore-ETH Centre in close collaboration with the [Urban Analytics Lab (UAL)](https://ual.sg/) at the National University of Singapore (NUS).
+
+Raw imagery and perception labels are taken from the [SPECS](https://huggingface.co/datasets/matiasqr/specs) dataset.
