Reflects the rate of growth in housing construction. Housing Starts act as an indicator measuring the strength of Canada's construction sector and housing market. Economists also use the figure as a leading indicator for the economy as a whole due to Housing Starts' sensitivity to changes in the business cycle. Housing Starts slow at the onset of a recession and quickly grow at the beginning of an economic boom; consequently, a high Housing Starts figure forecasts strong economic growth.

The headline figure is the percentage change in new home starts.

The key gauge for inflation in Canada. Simply put, inflation reflects a decline in the purchasing power of the Canadian Dollar, meaning each Dollar buys fewer goods and services. CPI is the most obvious way to measure changes in purchasing power - the report tracks changes in the price of a basket of goods and services that a typical Canadian household might purchase. An increase in the index indicates that it takes more Dollars to purchase this same set of basic consumer items.

As the most important indicator of inflation in Canada , Consumer Price figures are closely followed by Canada 's central bank. The Bank of Canada has a target inflation band of 1 - 3 % and uses CPI and Core CPI as its principle gauge (the Bank of Canada posts inflation targets and CPI on their homepage). A rising CPI may prompt the central bank to raise interest rates in order to manage inflation and slow economic growth. Higher interest rates make holding the Dollar more attractive to foreign investors, and this higher level of demand will place upward pressure on the value of the Dollar.

CPI Excluding Core Eight

The Consumer Price Index excluding eight items which the Bank of Canada has deemed to have the most volatility from month to month. The goods omitted tend to fluctuate idiosyncratically and may distort CPI data. The headline figure for CPI is the percentage change in the index on a month to month and year to year basis.

Note : These Eight items include: fruit, vegetables, gasoline, fuel oil, natural gas, mortgage interest, inter-city transportation and tobacco products. Changes in the CPI Excluding the Core 8 are recognized as a better indicator of inflation than the regular CPI. The headline figure is reported as a percent change on both the month to month and year to year basis.

CManufacturing Shipments - also known as "shipments of goods of own manufacture" - report the production of goods produced by Canadian establishments in the "Manufacturing Sector (NAICS 31-33)". It measures the Dollar value, not the quantity of manufactured goods produced.

  Survey assessing business conditions and expectations of manufacturing executives in New York . Though the survey is relatively new and New York has a considerably small number of manufacturers, the report has shown a promising correlation to the Philadelphia Fed Index and the market moving ISM Manufacturing Survey. Thus Empire serves as a useful earlier indicator of overall manufacturing in the US .

Results are calculated as the difference between percentage of positive and negative scores; zero acts as the breakeven point. A high figure is bullish for the dollar, indicating positive business sentiment conducive to growth in production. A low or negative number signals poor business conditions.

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.
