The Lockdown Weighted inflation CPILW for April 2021
CPILW rose significantly to 1.5% in April from 0.8% in March. The official CPIH measure of inflation also rose significantly to 1.6% from 1.0% the previous month. The gap between the official measure and the measure using lockdown weights has remained small but positive. This contrasts with the months prior to December 2020, when CPIH was less than CPILW, indicating that the official measure tended to understate inflation in that period.
