﻿HOW 
  THE 
  SKIER 
  POPULATION 
  ESTIMATE 
  WAS 
  DERIVED 
  

  

  The 
  skier 
  population 
  is 
  composed 
  of 
  two 
  groups 
  - 
  -those 
  who 
  actively 
  ski 
  during 
  

   any 
  specific 
  season 
  and 
  those 
  who 
  don't. 
  Data 
  in 
  this 
  report 
  apply 
  only 
  to 
  that 
  part 
  of 
  

   the 
  total 
  skier 
  population 
  that 
  was 
  active 
  during 
  the 
  1964-65 
  skiing 
  season. 
  

  

  The 
  procedure 
  used 
  to 
  estimate 
  the 
  number 
  of 
  active 
  skiers 
  was 
  to 
  divide 
  the 
  

   total 
  number 
  of 
  skier 
  visits 
  made 
  to 
  ski 
  areas 
  within 
  each 
  State 
  during 
  the 
  season 
  by 
  

   the 
  average 
  number 
  of 
  visits 
  (days) 
  per 
  skier 
  reported 
  by 
  skiers 
  contacted 
  during 
  the 
  

   survey. 
  

  

  Not 
  all 
  of 
  the 
  skier 
  visits 
  to 
  a 
  State, 
  however, 
  were 
  made 
  by 
  residents 
  of 
  that 
  

   State. 
  For 
  this 
  reason, 
  it 
  was 
  necessary 
  to 
  determine 
  the 
  proportion 
  of 
  total 
  State 
  

   visits 
  made 
  by 
  residents 
  of 
  that 
  State, 
  residents 
  of 
  other 
  Western 
  States, 
  and 
  residents 
  

   of 
  non 
  -Western 
  States. 
  These 
  proportions 
  were 
  derived 
  from 
  the 
  skier 
  sample 
  in 
  

   which 
  each 
  skier 
  reported 
  the 
  number 
  of 
  ski 
  visits 
  he 
  made 
  to 
  each 
  Western 
  State 
  during 
  

   the 
  season. 
  For 
  example: 
  

  

  1. 
  One 
  million 
  visits 
  were 
  reported 
  by 
  ski 
  area 
  operators 
  in 
  State 
  A. 
  

  

  2. 
  Skiers 
  questioned 
  reported 
  making 
  a 
  total 
  of 
  1,000 
  visits 
  to 
  ski 
  areas 
  in 
  

   State 
  A 
  in 
  the 
  following 
  proportions: 
  

  

  a. 
  Residents 
  made 
  80 
  percent 
  of 
  the 
  visits 
  to 
  ski 
  areas 
  in 
  State 
  A. 
  

  

  b. 
  Nonresidents 
  from 
  other 
  Western 
  States 
  made 
  15 
  percent 
  of 
  the 
  visits 
  in 
  

   State 
  A. 
  

  

  c. 
  Nonresidents 
  from 
  other 
  non 
  -Western 
  States 
  made 
  5 
  percent 
  of 
  the 
  visits. 
  

  

  3. 
  The 
  total 
  1 
  million 
  skier 
  visits 
  to 
  State 
  A 
  can 
  then 
  be 
  attributed 
  to 
  the 
  three 
  

   skier 
  resident 
  classes 
  as 
  follows: 
  

  

  a. 
  Residents, 
  800, 
  000 
  visits 
  

  

  b. 
  Nonresidents 
  from 
  other 
  Western 
  States, 
  150, 
  000 
  visits 
  

  

  c. 
  Nonresidents 
  from 
  non 
  -Western 
  States, 
  50,000 
  visits 
  

  

  4. 
  If 
  the 
  average 
  number 
  of 
  visits 
  per 
  skier 
  during 
  the 
  season 
  by 
  skiers 
  in 
  each 
  

   of 
  these 
  three 
  residency 
  classes 
  were 
  10, 
  5, 
  and 
  8 
  visits, 
  respectively, 
  the 
  

   number 
  of 
  active 
  skiers 
  who 
  used 
  ski 
  areas 
  with 
  the 
  State 
  can 
  then 
  be 
  calcu- 
  

   lated 
  as 
  follows: 
  

  

  a. 
  

  

  800,000 
  visits 
  by 
  residents 
  

  

  80,000

  skiers

  visits/yr

  b. 
  

  

  150, 
  000 
  visits 
  by 
  nonresidents 
  

   from 
  other 
  Western 
  States
