Reasons For Discrepancies Between National and International (JMP) Coverage Estimates
The indicators used by the JMP are controversial because they cannot always match cultural and local perceptions of what works or not, and can differ from national estimates. Discrepancies between national and international (JMP) coverage estimates are generally due to one or more of the following:
1) Use of different definitions of access including poorly defined access categories
2) Exclusion of users of shared sanitation facilities of an otherwise improved type, from those considered to have improved sanitation
3) Use of latest survey or census findings vs. use of an interpolated estimates based on linear regression
4) Use of different population estimates, including a different distribution of urban and rural populations
5) Use of “old” estimates which do not reflect the latest or all findings from new sample surveys or a new census
6) Use of “reported” line ministry data vs. use of independently verifiable data from sample surveys or censuses

Famous quotes containing the words reasons, national and/or estimates:
“While there are practical and sometimes moral reasons for the decomposition of the family, it coincides neither with what most people in society say they desire nor, especially in the case of children, with their best interests.”
—Robert Neelly Bellah (20th century)
“There is no national science just as there is no national multiplication table; anything that is national is not scientific.”
—Anton Pavlovich Chekhov (1860–1904)
“Writing a book I have found to be like building a house. A man forms a plan, and collects materials. He thinks he has enough to raise a large and stately edifice; but after he has arranged, compacted and polished, his work turns out to be a very small performance. The authour however like the builder, knows how much labour his work has cost him; and therefore estimates it at a higher rate than other people think it deserves,”
—James Boswell (1740–1795)
