The official govt figures for inflation are based on a "basket of goods and services" that probably reflects nobody's actual reality.
From a govt web site (
http://www.bls.gov/cpi/cpifaq.htm#Question_6 -- lots of info with links to more):
The CPI frequently is called a cost-of-living index, but it differs in important ways from a complete cost-of-living measure.
...
The Consumer Price Index (CPI) is a measure of the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services.
...
FOOD AND BEVERAGES (breakfast cereal, milk, coffee, chicken, wine, service meals and snacks)
HOUSING (rent of primary residence, owners' equivalent rent, fuel oil, bedroom furniture)
APPAREL (men's shirts and sweaters, women's dresses, jewelry)
TRANSPORTATION (new vehicles, airline fares, gasoline, motor vehicle insurance)
MEDICAL CARE (prescription drugs and medical supplies, physicians' services, eyeglasses and eye care, hospital services)
RECREATION (televisions, pets and pet products, sports equipment, admissions);
EDUCATION AND COMMUNICATION (college tuition, postage, telephone services, computer software and accessories); <what, no Internet access?!>
OTHER GOODS AND SERVICES (tobacco and smoking products, haircuts and other personal services, funeral expenses).
Also included within these major groups are various government-charged user fees, such as water and sewerage charges, auto registration fees, and vehicle tolls. In addition, the CPI includes taxes (such as sales and excise taxes) that are directly associated with the prices of specific goods and services. However, the CPI excludes taxes (such as income and Social Security taxes) not directly associated with the purchase of consumer goods and services.
The CPI does not include investment items, such as stocks, bonds, real estate, and life insurance. (These items relate to savings and not to day-to-day consumption expenses.)
For each of the more than 200 item categories, using scientific statistical procedures, the Bureau has chosen samples of several hundred specific items within selected business establishments frequented by consumers to represent the thousands of varieties available in the marketplace. For example, in a given supermarket, the Bureau may choose a plastic bag of golden delicious apples, U.S. extra fancy grade, weighing 4.4 pounds to represent the Apples category.

I find this fascinating! For example, they inlcude the cost of funerals but not the cost of weddings, investing, repairs, home remodeling, legal services, cleaning help, nursing home/assisted living, or vacations. They include the cost of renting a single ramily house, but not the cost of buying (or selling) one or the property taxes or HOA fees, or even Social Security taxes. Not to mention that as one ages, one generally needs more convenience items and services--especially more heat as I'm finding with my 80-yr-old mother (who keeps her house at 78 all winter).
The CPI seems unsatisfacotry for the purpose we put it to (retirement financial planning). I'm glad this topic came up. I've been using 4% as my inflation rate, but I'm gonna switch to 5 or 6%.
