Construction Survey

The purpose is to provide data on some essential short-term economic factors within the construction industry. The survey is a qualitative assessment on developments over the past three months and expected developments over the next three month, based on the variables employment, sales, prices, new orders and limits to production. Also is asked how many months work is accounted for in the order book.

COVID-19 has not affected the basis and methodology of these statistics itself, but three COVID-19-related questions have been added to the survey. The results of which are enumerated in the same way as for the business cycle indicators, described in this Documentation of Statistics.

The results on the new questions are published under Experimental Statistics (in Danish), with a link to a background document. The final figures of the month are released on the penultimate working day of the month, with a preliminary release in the middle of the month.

Data description

The purpose of the tendency survey for the construction industry is to provide a fast and up-to-date picture of conditions and expectations in the construction industry. As from the 1st quarter of 1970 Statistics Denmark has conducted a tendency survey for the construction industry. From 1970 to 1997 the tendency survey was conducted quarterly. To harmonize with the surveys conducted by other EU member states, the Danish tendency survey has been conducted monthly since January 1998. This change also implied that further questions were added to the survey. The survey is directly connected to and defined by the Business and Consumer Survey joint harmonized programme as managed by the Directorate-Generale for Economic and Financial Affairs (DG ECFIN), European Commission. Within same programme is also carried out monthly tendency surveys on Manufacturing Industries, Services, Retail Trade and Consumer expectations as well as the biannual survey on Manufacturing Industry Investments.

The survey is a qualitative assessment on developments over the past three months and expected developments over the next three month, based on the variables employment, sales and prices The questionaire is filled in by ticking decrease, unchanged, or increase. Furthermore is asked to the current order book level and also is asked how many months work is accounted for in the order book. Finally the respondents are also asked if there currently are any factors limiting the building activity of the respondent.

Classification system

The industries in the survey is defined by DB07 , which is the Danish industrial classification system similar to the international NACE rev. 2 system.

The division of industry groups are (DB07 groups in brackets):

41000 Construction of buildings: 411000, 412000 42000 Civil engineering: 421000,422000,429000,421100,421200,421300,422100,422200,429100,429900 43201 Electrical installation etc.: 432100,432900 432200 Plumbing, heat and air-conditioning installation: 432200 43301 Joinery installation etc.: 433100,433200,433300 43302 Painting and Glazing etc: 433410,433420,433900 439910 Bricklayers: 439910 43003 Other specialized construction activities: 431100,431200,431300,439100,439990

Statistical concepts and definitions

Business Tendency Survey: Business Tendency Survey. Compared to traditional statistical surveys, which only cover one or a few related variables from one area of the economy, business surveys collect information about a wide range of variables selected for their ability, when analysed together, to give an overall picture of a sector of the economy. The surveys include questions such as the volume of production, order books, order inflow, stocks of finished goods , exports, employment and prices. The range of information covered by business surveys also goes beyond variables normally captured by classical statistics. Qualitative information may be collected for variables, which are difficult or impossible to measure by conventional methods such as: capacity utilisation, production bottlenecks and views on the overall economic situation.

Confidence Indicator: An indicator for the present position in the business cycle. The marked economy evolves in cycles between boom, decrease, recession and upswing.

Composite Confidence Indicator: Composite indicators are calculated as the simple arithmetic average of the (seasonally adjusted if possible) balances of answers to specific questions chosen from the full set of questions in the survey. In the case of Retail Trade survey the composite indicator reflects the average of the three indicators on Sales over the past three month, the present Volume of stock and Sales expectations over the next three months.

Balance: Balances are the difference between positive and negative answering options, measured as percentage points of total answers. In particular, if a question has three alternative options, “positive” (“up”, “more”, “more than sufficient”, “good”, “too large”, “increase”, “improve”, etc.), “neutral” (“unchanged”, “as much”, “sufficient”, “satisfactory”, “adequate”, etc.) and “negative” (“down”, “less”, “not sufficient”, “too small”, “decline”, etc.), and if P, E and M (with P+E+M=100) denote the percentages of respondents having chosen respectively the option positive, neutral, and negative, the balance is calculated as B = P - M
