The Center for European Economic Research (ZEW), queries financial experts throughout Europe every month in order to make a medium-term forecast about the economic situation. Eurozone ZEW Indicator of Economic Sentiment Assesses future economic expectations for the whole Eurozone. The results are summarized as the number of positive responses minus the number of negative responses. A higher headline figure indicates a positive expectation for Euro-zone economy.

Technical Note on Headline Number : The results of the survey are always presented as the difference between those experts that optimistic and those are pessimistic. For instance if 25 percent of analysts expect improvement, 35 percent expect decline, and 40 percent expect no change, the headline figure is -10.

Measures the volume change of output of the manufacturing and energy sector. The industrial sector contributes to only a quarter of the Eurozone GDP. However, most variations in the GDP come from the industrial sector, whereas other sectors that contribute far more to national output historically have been very consistent regardless of economic cycles. That is why tracking industrial production is very important for forecasting GDP changes.

Note: The Industrial Production figure can be adjusted for the number of working days in the given time period and/or seasonally to account for weather related changes in production.

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.

An aggregated measure of the sales of retail goods over a stated time period, typically based on a data sampling that is extrapolated to model an entire country. In the U.S., the retail sales report is a monthly economic indicator compiled and released by the Census Bureau and the Department of Commerce. The report covers the previous month, and is released about two weeks after the month-end. Comparisons are made against historical data; year-over-year comparisons are the most-reported metric because they account for the seasonality of consumer-based retail.

This index reflects import price change per month.
