The
year on year inflation rate (annual percentage change) for
the month of November 2006 as measured by the all items Consumer
Price Index (CPI) stood at 1098.8 percent, gaining 28.6 percentage
points on the October rate of 1070.2 percent.
This
means that prices as measured by the all items CPI increased by
an average of 1098.8 percent between November 2005 and November
2006.
- The year-on-year
inflation rate is given by the percentage change in the index
of the relevant month of the current year compared with the
index of the same month in the previous year.
Food
and Non Alcoholic beverages inflation prone to transitory shocks
stood at 1056.6 percent whilst Non-food inflation stood at 1123.5
percent.
The
month on month inflation rate (monthly percentage change) in November
2006 was 30.1 percent gaining 2.6 percentage points on the October
2006 rate of 27.5 percent.
This
means that prices as measured by the all items CPI increased by
an average of 30.1 percent from October 2006 to November 2006.
- The month-on-month
inflation rate is given by the percentage change in the index
of the relevant month of the current year compared with the
index of the previous month in the current year.
The
month on month Food and Non Alcoholic Beverages inflation stood
at 31.6 percent in November 2006. The month on month non-food inflation
stood at 29.3 percent gaining 4.4 percentage points on the October
2006 rate of 24.9 percent.
The CPI
for the month ending November 2006 stood at 488604.6 compared to
375478.8 in October 2006 and 40758.1 in November 2005.
- The direction
and magnitude of the rate of change in year on year inflation
for a relevant month depends on how both the numerator and the
denominator (the base) change during the same month in the current
and the previous year.
The
change in average price of the basket from October 2006 to November
2006 was higher (30.1%) as measured by the change in the price index,
than the change in average price of the same basket from October
2005 to November 2005 (27.0%). That explains the rise in year on
year inflation in November 2006.
The new Consumer Price Index
With
effect from June 2005, the CSO is publishing the new Consumer Price
Index (CPI) with new weights and a new classification in accordance
with international guidelines. The shift to a new classification
of Individual Consumption by Purpose (COICOP) has resulted in the
increase in the number of sub-groups from 34 to 68 and the number
of major groups has increased from 10 to 12.
The
number of items in the CPI basket has also been increased from 337
to 428.As a result, the CPI has become more disaggregated. However,
in the short term there would be lack of direct comparison of certain
sub-indices for which monthly and annual comparison should be achieved
in July 2005 and June 2006, respectively.
Due
to the reclassification that has been done, some new sub-groups
were created by moving individual items from one sub-group to another
sub-group. For instance, the major group "Transport and Communication"
in the previous classification was split into "Transport"
and "Communication" major groups under the new set up.
A totally new major group called "Restaurants, Cafes and Hotels"
was created.
The
implementation of the COICOP classification is also part of the
harmonisation project of Consumer Price Indices in different regions
like the SADC region. All member states are supposed to adopt the
new procedure to enable inter country comparisons of the CPI and
the rate of inflation.
The
indices prior to June 2005 were all re-referenced to 2001=100. In
principle, these indices do not aggregate. However, the rates of
inflation remain the same under different weight regimes as the
relative magnitude of indices is maintained. The new weights are
therefore applicable from June 2005 onwards.
Linking
the 1995=100 with the 2001=100 base at all items level
Users
who wish to continue using the old series (the 1995=100 base) are
advised to divide the current all items index with a new base of
(2001=100) by a conversion factor of 0.12384622. For instance if
the CSO had continued with the old base (1995=100), the June 2005
all items CPI was going to be 99 754.35.For instance the July 2005
CPI at 1995 prices is 146599.5.
