APPENDIX E: HISTORICAL DATA FOR THE COMMONWEALTH BUDGET
SECTOR
Table E1 provides
details of the budget aggregates for the period 1960-61
to 2000-01. The underlying budget balance is revenue
minus outlays excluding net advances to other sectors.
Net advances comprise net loans from the budget (new
policy loans and advances less repayments) and net
equity injections (injections/purchases of equity less
equity sales). Classification differences and revisions,
as well as changes to the structure of the budget,
can impact on comparisons over such an extended period.
In particular, there are some classification differences
in the data relating to the period prior to 1976-77.
This means that data for the earlier period may not
be entirely consistent with that for 1976-77 and later
years.
Table E2 provides
details of tax, non-tax and total revenue for the period
1960-61 to 2000-01. These revenue data are compiled
on a consistent basis from 1976-77.
Other factors which affect the comparability of budget
aggregates between years are:
- adjustments in the coverage of agencies included in
the accounts of the Commonwealth budget sector;
- transfers of taxing powers between the Commonwealth
and the States;
- other changes in financial arrangements between the
Commonwealth budget sector, Commonwealth non-budget
sector agencies and the State/local government sector;
and
- changes in arrangements for transfer payments where
tax concessions or rebates are replaced by payments
through the social security system. This has the effect
of increasing both revenue and outlays as compared
with earlier periods, but not changing balances. Changes
in the opposite direction (tax expenditures replacing
outlays) reduce both outlays and revenue.
While approximate adjustments can be made to identify
trends in budget aggregates on a generally consistent
basis, the further back this analysis is taken, the
less manageable that task becomes.
A detailed discussion of the comparability of budget
aggregates since 1960-61 is provided in Statement 5
of Budget Paper No. 1, 1992-93.
Further details of the coverage of the budget sector
are provided in Statement
7. Detail on the changes in the classification
of budget transactions are provided in Appendix
D of this Statement.
