This child item describes Python code used to estimate average yearly and monthly tourism per 1000 residents within public-supply water service areas. Increases in population due to tourism may impact amounts of water used by public-supply water systems. This data release contains model input datasets, Python code used to develop the tourism information, and output estimates of tourism. This dataset is part of a larger data release using machine learning to predict public supply water use for 12-digit hydrologic units from 2000-2020. Output from this code was used as an input feature in the public supply delivery and water use machine learning models. This page includes the following files: tourism_input_data.zip - a zip file containing input data sets used by the tourism Python code tourism_output.zip - a zip file with output produced by the tourism Python code README.txt - a README file describing the data files and code requirements tourism_study_code.zip - a zip file containing the Python code used to create the tourism feature variable
