First, LICO is far too complex to be a useful poverty line. Most people, including academics, don't have the foggiest notion of how LICO is constructed and how it is rebased. This leads to frequent misinterpretations in the media and in some policy documents. Some concepts are intrinsically complex and require, of necessity, indirect and convoluted measurement. That is not the case with poverty.
Poverty is a state of serious deprivation.
It should be possible to translate that concept into a fairly straightforward statistical measure that almost everyone can understand. Second, LICO is a relative measure. It is intimately related to average living standards through its connection to average consumption of a given basket of commodities through the process of occasional rebasing. This means that the LICO lines rise with living standards, although, perhaps, not at the same rate. What matters in measuring relative poverty is the extent of inequality in society.
