Measures changes in the volume of output produced by the manufacturing, mining, and utility sectors in the USA. Because industrial production is a measure of output volume rather than dollar value, the figure is not distorted by inflation and is considered a more "pure" indicator for US industry. Though industrial production only accounts for a relatively small portion of the GDP, it accounts for most of the volatility in GDP and is considered highly sensitive to changes in interest rate and consumer demand. Therefore understanding trends in this figure are important to forecasting the GDP. High or rising Industrial Production figures suggest increased production and economic expansion. However, uncontrolled levels of production and consumption can spark inflation.

The figure varies significantly month to month due to the fact that seasonal and weather related factors often alter factory production and utility demand. Because of this volatility, the report has limited market impact.

The figure is calculated as a weighted aggregate of goods and reported in headlines as a percent change from previous months.

The UK Manufacturing Production index is compiled by the National Statistics Office and measures the level of manufacturing output. It is an important indicator since it measures growth in the country’s manufacturing industry which is a major component of Gross Domestic Product. A low reading is considered bearish for the Sterling.

Capacity Utilization measures the extent to which US manufacturing companies make use of their installed productive capacity (factories and machinery). Capacity Utilization reflects overall growth and demand in the economy, rising when the economy is vibrant, and falling when demand softens. High capacity utilization also exerts inflationary pressures as scarce resources are in higher demand. However, it may also lead to new capital investments, such as new plants, that promote growth in the future.

A timely gauge of home sales and expectations for future home building. Based on a small sample of homebuilders, the Housing Market Index is a timely indicator of future US home sales. However, as the index is not as comprehensive as formal housing reports like new home sales or MBA mortgage applications, the index acts more like a supplemental indicator for predicting housing trends.

As such, the NAHB Housing Market Index is still able to provide general insight to where the housing market is heading. Given that new home sales reflect 'big ticket' items that require construction and investment, the housing market is often viewed as an indicator of the direction of the economy as a whole. Growth in the housing market will spur subsequent spending, generating demand for goods and services and the employees who provide them.

The report headline is expressed in percentage change from the previous month. The NAHB Housing Market Index divides the Single-Family Sales data into three categories: Present, Next 6 Months and Prospective Buyers Traffic.
