Trend by Program

Each panel has its own scale so the shape of every trend is visible; 2020 (shaded) is the per-class booking change. Use the buttons to switch measure; % of member families is the fairest popularity measure.

Tennis

Tennis: New, Returning and Reactivated Participants

Youth = Youth Tennis and Tennis Team; Adult = drills and adult socials. Returning = also played the previous season. Reactivated = played in an earlier season, but not last year. A junior who moves to adult programs counts as First Time in Adult Tennis.

Tennis: How Much Each Participant Plays

Share of participants by number of classes attended in the season.

Tennis: Participation by Age

Default view: share of members in each age band who took part. Switch to Participants for headcounts.

Tennis: Participation by Bond Age

Share of member families in each bond-age band (years since original bond date) with a participant.

Adult Tennis: Participation by Bond Age

Same as above, counting only families with someone in adult drills or adult socials.

Tennis: Participants by Program Type

Unique participants per subcategory, on a shared scale. One person can appear in more than one panel.

Tennis by Year

Every tennis metric in one table. Click a column header (ⓘ) to see how it is calculated.

Note * 2020: tennis switched from multi-week session packages to booking each class separately. The new reservation style artificially inflated 2020 numbers, so don't compare 2020 directly with other years.

Column Definitions

Year: Season year: the year of the first class date (the booking date when class dates are missing).
Unique Participants: Distinct people (family account + name) with at least one active, non-cancelled reservation in this program during the season.
Reservations: Count of active (non-cancelled) reservations. Since 2020 tennis books each class separately, so this jumps for format reasons rather than demand.
Youth (<18): Unique participants under 18 that season (season year − birth year from the member roster).
Adults: Unique participants aged 18 or older that season.
Median Age: Median age of unique participants that season (season year − birth year).
New-Family Uptake: Share of member families bonded this season or last (bond age 0–1) with at least one tennis participant.
Youth Back Next Year: Share of this season's youth participants (under 18) active in any tennis program the following season. Blank for the latest season.
Youth Later in Adult Programs: This season's youth participants who appear in an adult tennis program (drills or socials, aged 18+) in any later season.
Families: 1 Player: Participating families with exactly one member playing tennis that season.
2 Players: Participating families with exactly two members playing tennis that season.
3+ Players: Participating families with three or more members playing tennis that season.

Column Definitions

Year: Season year: the year of the first class date (the booking date when class dates are missing).
Unique Participants: Distinct people (family account + name) with at least one active, non-cancelled reservation in this program during the season.
Reservations: Count of active (non-cancelled) reservations. Since 2020 tennis books each class separately, so this jumps for format reasons rather than demand.
Participating Families: Distinct member family accounts with at least one participant. Youth programs count only accounts holding a family membership.
Total Member Families: Member accounts on the swim family roster that season. Youth programs count only accounts holding a family membership (Adult and Employee memberships have no eligible children).
% of Member Families: Participating Families ÷ Total Member Families.
First Time: Participants never active in this program in any earlier season. Blank for the first season of data (2013), since earlier history is unknown.
Back Next Year: Share of this season's participants who are active in this program again the following season. Blank for the latest season.
Offerings: Distinct classes/camps in the eSoft camp summary report whose first class is in this season.
Avg Enrolled / Offering: Average registrations per offering (clients registered, from the eSoft camp summary report).
Cancelled: Cancelled reservations ÷ all reservations (active + cancelled).
Revenue †: Sum of the revenue field on active reservations, from eSoft. Nominal dollars; not audited.
Revenue / Person †: Revenue ÷ Unique Participants. Based on unaudited eSoft revenue.

Definitions

Booking Format Change (Shaded 2020): Through 2019 most tennis reservations covered a 4–6 week session. In 2020 every class date was booked separately, and from 2021 reservations cover 1–2 dates. Reservation counts therefore jump for reasons that have nothing to do with demand; unique participants and % of member families are comparable across years.
Participant: A person (family account + name) with at least one active, non-cancelled reservation in the season.
% of Member Families: Member families with at least one participant ÷ all member families that year (swim family roster). This corrects for the club growing from about 450 to 560 families.
Age and Bond Age: Age is season year − birth year, from the member roster (matched for ~99% of tennis participants). Bond age is season year − year of the family's original bond date. Rates divide participants in a band by members in the same band that year.
Offerings: Distinct classes in the camp summary report and their average registrations. There is no capacity field, so fill rate is not available.
