Background For this analysis, you will be working with quarterly municipal water demand data from 1996 through 2025, provided in “quarterly_water_usage.csv”. Over this period, water demand is affected by seasonal patterns related to weather and usage (such as higher demand during warmer months) as well as long-term changes like population growth and shifting consumption habits. As a result, this makes the dataset well-suited for time series analysis. By working with this data, you will explore trends, seasonality, and short-term variation in water demand and apply time series methods to better understand and model how water usage changes over time.
