Two proxy measures of access to basic health-care services are used to calculate the degree of inaccessibility: a service use-related indicator and a staff-related indicator. The service use-related indicator is the percentage of live births not attended by a qualified health professional. The staff-related indicator measures the shortfall in the minimum number of health professionals. Higher values of this indicator indicate a greater deficit. The data available on these two indicators for countries in the Asia-Pacific region are summarized in table 5.
