CPI assesses changes in the cost of living by measuring changes consumer pay for a set of items. CPI serves as the headline figure for inflation. Simply put, inflation reflects a decline in the purchasing power of the dollar, where each dollar buys fewer goods and services. In terms of measuring inflation, CPI is the most obvious way to quantify changes in purchasing power. The report tracks changes in the price of a basket of goods and services that a typical American household might purchase. An increase in the Consumer Price Index indicates that it takes more dollars to purchase the same set basket of basic consumer items.

Inflation is generally bad news for the economy, causing instability, uncertainty and hardship. To address inflation, the Fed may raise interest rates. However, the Fed relies on the PCE Deflator as its primary gauge of inflation because the CPI does not account for the ability of consumer to substitute out of CPI's set. Price changes tend to cause consumers to switch from buying one good to a less expensive-other, a tendency that the fixed-basket CPI figure does not yet account for. Given that the PCE Deflator is a more comprehensive calculation, based on changes in consumption; it is the figure the Fed prefers.

The figure is released monthly, as either a month over month annualized percentage change, or percentage change for the full year. The figure is seasonally adjusted to account seasonal consumption patterns.

On A Technical Note: The CPI includes over 200 categories of goods and services included, divided into 8 main groups, each with a different weight: Housing, Transportation, Food, Medical Care, Education and Communication, Recreation, Apparel, and Other Goods and Services.

CPI Excluding Food and Energy - United States

The CPI is also reported excluding food and energy; two of its most volatile components. These components are particularly sensitive to temporary economic factors like oil prices, natural disasters and seasonal affects. Consequently, CPI excluding Food and Energy provides a more stable figure, but at the cost of overlooking two significant sectors in the economy (together food and energy comprise nearly a quarter of the goods included in the CPI).

The figure is the monthly percent change in the index.

Tracks the number of the employed in the country. A surge in new employment suggests higher spending potential and budding inflation pressures.

The percentage of individuals in the labor force who are without a job but actively seeking one. A higher Unemployment Rate is generally a drain on the economy. Not only does it mean that resources are not being fully utilized, but it also results in lower consumer spending as there are fewer workers receiving paychecks.

Note: The unemployment rate generally moves slowly, so changes of only a few tenths of a percent are still considered significant. Also note that the unemployment rate does not account for discouraged workers. Therefore, in an economically depressed environment, such as that which occurred in Cold War era East Germany, the Unemployment Rate may not accurately reflect the extent of problems.

modern award usually defines a part-time employee as an employee who is engaged to work less than an average of 38 ordinary hours per week and whose hours of work are reasonably predictable, with a guaranteed minimum number of hours of work. Work is usually performed on regular days of the week. A part-time employee will usually be entitled to the same employment conditions as a full-time employee, but on a pro rata basis compared to the full-time hours (usually 38 per week) prescribed under the applicable industrial instrument.
