Introduction

Estimating household expenditure on dwelling services in the GDP

Calculating PPPs for dwelling services

HOUSING

Rentals

Owner-occupied

Actual expenditure by households on rents for dwellings

Estimate of how much owner-occupiers would have paid in rent if not owning their dwellings

Choosing Methods to Apply

Are more than 25% of dwellings rented?

Are most rented dwellings either occupied by its citizens and not subsidized?

Are rented dwellings distributed evenly throughout the country?

YES

YES

NO

No

NO

Obtain expenditure weights by:

- estimating actual rents paid for rented dwellings

- applying the user cost method for owner-occupied dwellings.

YES

Obtain expenditure weights by:

- estimating actual rents paid for rented dwellings;

- imputing rents for owner-occupied dwellings using rents actually paid for similar dwellings.

Overall Validation Process

Rents (multiple times in a year)

Data Compilation

Initial data validation

Regional Level (Inter-country Validation)

Finalization of Data

Global Level (Inter-country Validation Across Regions)

intra country validation 1
Intra-country Validation 1

Rents Data

Rents and metadata to be added to the validation tool (excel)

Step 1

Rents and metadata to be checked for errors and discrepancies

Step 2

Step 3

Rents to be checked for sub-national plausibility based on NCA’s market knowledge

Sub-national comparison between rents with similar specifications

e.g. rents in the capital city < rents in rural area

 Populous regions generally have higher rents given similar specs

Step 4

Rents to be checked for temporal plausibility based on NCA’s market knowledge

  • Between collection periods (seasonal variability)
  • Between the 2005 and 2011 rounds
intra country validation 2
Intra-country Validation 2

Number of occupants divided by number of dwelling units needs to be plausible

Totals should be equal

Number of units with inside water is generally higher than number of units with private toilet

inter country validation
Inter-country validation

Rents Data

Quantity Data

Step 1

Convert rents in LCU to rents in common currency

Similar validation as basic editing from the intra-country process

Step 2

Analytical Tables (QT, DT)

Evaluation of completeness of Quality Indicators

Step 3

Temporal Analysis for Annual Data

Calculate quality-adjusted volume

Step 4

Together with Expenditure data, calculate Volume measure

and check plausibility

Together with Expenditure data, calculate Indirect PPPs

and check plausibility

Step 5

Compare both results
