As a course owner/operator I am looking for a good "mix" of ages. Too many young members can be a bad thing as well even though it is unlikely to happen.
My club is a private golf club of 600 members (We cap full memberships at 475 and seniors at 125). About 20-25% of my members are under 40, 55%-60% are between 40 and 55 and about 20-25% are over 55.
My fees are "affordable" for the area--$7500 for a full family membership ($259 monthly dues) and a senior membership is $2500 and $200 in monthly dues.
To attract the under 40's they can pay $2500 with their application, $2500 4 years later and the final $2500 seven years later. If they are not still members of the club (moved away for example) they do not owe the second or third payments. Also, dues for someone in their 20s are reduced 25% from the full rate and for the thirtysomethings the reduction is 15%.
Average "life expectancy" for a private memership is right at 7 years in my region so my thinking is that giving a young person that time period is fair and affordable. Also, the club business is about dues, dues and more dues. I want to make it as easy as possible to get qualified applicants in to start charging them dues!
My senior membership is only available to people over 55 and allows weekday golf only. Seniors are crucial though to our success as they keep our course and tee sheet busy during the week between 8:00 and 11:30, normally a dead time for many private clubs. In effect I have 600 members during the week and just 475 on weekends and holidays which are prime times.
Each group tends to play at diferent times and by keeping a good mix I can maximize my tee sheet. If you had too many youngsters or seniors, they would compete for similar times and your course would seem crowded even with fewer members. Conversely, a full and active club can keep people happy re: tee times if the demand is spread out.
BTW, unlike some private courses around me, in 33 years we have never had to use any type of "lottery" system for our members to book times. I personally don't know why someone would join a private club only to have to get in a lottery for tee times, but some do.
Ideally, our regular 40-55 year old members "progress" to senior statues and make room for other full members (we currently have a 4 1/2 month waiting list). Also, as the seniors can no longer play golf, they can then move to clubhouse status and come eat lunches, play cards, etc.
I know there is a lot of talk that clubs must cater to the younger families by offering every possible amenity--babysitting, tennis teams, pottery classes, aerobics, etc. the trouble with that model is that in order to offer something for everyone, you have to charge a lot of money. Time and other pressures easily pull young families away and how many young families with kids can justify $20k-$50k in initiation fees (even paid over time) plus $6k a year in dues!
My club is few frills--very good golf course but no swim, no tennis and our food is more burger and beer than filet and red wine, but I can keep my cost down and the young guy is able to justify my expense to his family.
Now the younger family guy dosn't have to join a "lifestyle" club and spend every waking moment there with his family to justify the expense. For $2500 down and $220 per month (if he is in his 30's) he can play private golf for 4 years before he owes a second $2500.
For a while I offered a Conditional Membership geared to the person who may be in Atlanta for only a few years. It was a two year membership for an ID of $2500 and monthly dues of $300 per month. They had to pay more a month since they did not "commit" to the entire $7500. Again, I was looking at the 40-50 something who was likely to be transferred. Given my current membership situation, we do not offer it at this time though it was very popular in the mid 1990's.
(My club is in the Atlanta area just north in Alpharetta).
