3. Estimation of households’ stock of land
underlying buildings and structures
3.1
•
Background information
Characteristics of the “old” approach to the estimation of land underlying
buildings and structures by the Bundesbank
1.
Approach was inextricably linked with the estimation of fixed assets
2.
Approach was based on an updating procedure of former estimates of
fixed assets by Destatis under ESA 1979 and former land estimates
by the German Institute for Economic Research (DIW) and the
Deutsche Bundesbank
• Introduction of Destatis’ sectoral compilation of fixed assets required a “new”
approach to the estimation of land underlying buildings and structures
8
3.2
Data requirements
Aim of the estimation procedure was to compile
•
•
Market value and real stock of land underlying buildings and structures
(AN.2111) for households including non-profit institutions serving households
(S.14+S.15) for the period from 1991 to 2006
Breakdown of the results into
1. part of land (AN.2111) underlying dwellings (AN.1111)
2. part of land (AN.2111) underlying other buildings and structures
(AN.1112)
9
3.3
Data sources
1. Statistics on purchase values of building land published by Destatis
•
•
•
•
Transactions: sales volumes of building land (in sq.km) from 1964 up to 2007 (annual
data)
Transaction/market prices (in €/sqm)
Breakdown by building areas (business area, mixed business and residential area,
residential area, industrial area, village area)
No breakdown by sector and no breakdown into land underlying dwellings and land
underlying other buildings and structures according to ESA 1995
2. Statistics on the area of land classified by actual uses published by Destatis
•
•
•
Breakdown of the whole economy’s stock of land by kinds-of-use (in sq.km)
(quadrennial data: 1992, 1996, 2000, 2004)
Definition of item “areas and open areas underlying buildings” corresponds to land
underlying buildings and structures (AN.2111) according to ESA 1995.
No breakdown into land underlying dwellings and land underlying other buildings and
structures according to ESA 1995; no information on land (market) prices
10
3.4
Estimation procedure
Step 1:
Stock-flow calculation of land underlying buildings and structures at the
total economy level (S.1) and breakdown by building areas (business
area, mixed business and residential area, residential area, industrial
area, village area) from 1991 to 2006
Step 2:
Breakdown of the stock-flow calculation into land underlying dwellings and
land underlying other buildings and structures at the total economy level
(S.1)
Step 3:
Breakdown of land underlying dwellings and land underlying other
buildings and structures by institutional sector

Assessment
• Estimation approach led to considerable improvements in data quality
• But results have to interpreted with due care because
1.
sectoral breakdown is based on assumptions (no sectoral data
available)
2.
estimates can be only considered as a lower limit of the “true“
market value (no information on market values of land which is
already built-up)

Example of use: Compilation of integrated
financial and non-financial household sector
balance sheets

4.1 Compilation procedure
• Compilation of balance sheets for households including non-profit institutions
serving households (S.14+S.15) from 1992 to 2006
• Data sources and compilation:
1. Net stock of fixed assets (AN.11) from Destatis
2. Land underlying buildings and structures (AN.2111) from Bundesbank
3. Financial assets and liabilities (AF) from Bundesbank (financial accounts)
4. Net worth (B.90) compiled as residual

indebtedness, p. 298.
Notes: For Canada, Italy and the United States, data also include consumer durables. For Canada, Germany, France, Japan, the
United Kingdom and the United States, data also include non-residential buildings and fixed assets of unincorporated enterprises
and of non-profit institutions serving households, although coverage and valuation method may differ.

Conclusion
• Data quality and data availability regarding non-financial assets and respecting
household sector balance sheets have been improved considerably by the latest
work of Destatis and the Bundesbank
• Potential fields of improvement:
1.
Regarding data availability: for example, collection of data on nonfinancial assets which have not yet been covered by the current
compilation approach
2.
Regarding data quality: for example, development of reliable valuation
methods for land taking into account regional differences
