13 How do giving and participation overlap?

Each household is flagged is_donor (gave a SUCCEEDED individual gift), is_patron (registered for a performance), and is_class_taker (registered for a class).

Code

import pandas as pd
import plotly.express as px
from hh.io import read_parquet
from hh.viz import style, CATEGORICAL

hh = read_parquet("processed", "households_summary.parquet")
counts = (
    pd.Series(
        {
            "Donors": hh["is_donor"].sum(),
            "Patrons (performances)": hh["is_patron"].sum(),
            "Class-takers": hh["is_class_taker"].sum(),
            "Donor and class": (hh["is_donor"] & hh["is_class_taker"]).sum(),
            "Donor and patron": (hh["is_donor"] & hh["is_patron"]).sum(),
            "All three": (hh["is_donor"] & hh["is_patron"] & hh["is_class_taker"]).sum(),
        },
        name="households",
    )
    .reset_index()
    .rename(columns={"index": "group"})
)

Code

fig = px.bar(counts, x="group", y="households", color="group", color_discrete_sequence=CATEGORICAL)
fig.update_layout(showlegend=False, xaxis_title="", yaxis_title="Households")
fig.update_traces(hovertemplate="%{y:,.0f}<extra></extra>")
style(fig).show()
