+/-
GPI Contributions
Calculation Method

  Personal Consumption Largest component of both GDP and GPI
  Income Distribution Gini coefficient of distribution of income among households used as index number
  Weighted Personal Consumption Consumption divided by income distribution index
+ Value of Housework and Parenting Estimated number of hours per year times fixed dollar amount
+ Value of Volunteer Work Estimated number of hours per year times fixed dollar amount
+ Services of Consumer Durables Stock of cars, furniture, etc. times fixed percentage
+ Services of Highways and Streets Stock of highways times fixed percentage
- Cost of Crime Direct cost to households plus defensive expenditures to avoid crime
- Cost of Family Breakdown Divorce costs (lawyers plus effect on children) plus imputed cost of TV watching
- Loss of Leisure Time Difference between hours of leisure in 1969 and in other years times $11.20 per hour times labour force
- Cost of Underemployment Members of labour force working fewer hours than they want times the number of constrained hours per year they aren’t working times $11.20
- Cost of Consumer Durables Spending on cars, furniture, etc. (offsets Services of Consumer Durables)
- Cost of Commuting Out-of-pocket cost plus value of time spent commuting
- Cost of Household Pollution Abatement Spending by households on pollution abatement equipment –mostly for vehicles
- Cost of Automobile Accidents Vehicle damage and hospital costs
- Cost of Water Pollution Loss of water quality plus siltation
- Cost of Air Pollution Damage to vegetation, structures and aesthetics, soiling of cloth materials, acid rain, loss of urban property values (not health or mortality cost)
- Cost of Noise Pollution Reduced quality of human environment
- Loss of Wetlands Annualized value of the cumulative loss of services (purification, flood control, wildlife habitat) with value increasing exponentially as a result of scarcity value
- Loss of Farmland Annualized value of the cumulative loss of soil productivity based on assumption that inherent soil fertility will have greater value in the future as fertilizer and other inputs become more costly (soil erosion, soil compaction, urbanization)
- Depletion of Nonrenewable Resources Annualized value of the cumulative loss of potential services of resources that have been permanently lost (measured as increasing cost of what would be required to replace the cumulative quantity of energy resources produced domestically)
- Cost of Long-term Environmental Damage Current value of the cumulative expected costs of future damage from climate change and nuclear waste management (fossil fuel and nuclear energy consumption times fixed dollar value per unit)
- Cost of Ozone Depletion Cumulative world production of CFC-11 and CFC-12 times fixed dollar amount per unit
- Loss of Old-Growth Forests Cumulative value of the loss of ecological services from old-growth forest plus damage from forest roads
+ Net Capital Investment Change in stock of fixed capital minus change in stock of capital required for new workers equals net additional stock available for all workers (swings modified by use of rolling averages)
+ Net Foreign Lending or Borrowing Change in the net international position (corresponds to change in current trade balance) smoothed by using a five-year rolling average
  Genuine Progress Indicator Sum of above calculations
