I. Background WHY THE NEED TO REFINE THE METHODOLOGY? HAS THE DEFINITION OF POVERTY CHANGED? 1. The definition of poverty did not change. The refinements are only meant t b tt measure the poor. fi t l t to better th 2. It is a standard practice among official statisticians in national statistical systems all over the world to refine and update methodologies and statistical frameworks to better reflect current phenomena. 3. The UN Statistical Commission prescribes international g standards and guidelines on statistical measurement and practices but there is no international standard on measuring poverty.

I. Background WHY THE NEED TO REVISE THE METHODOLOGY? HAS THE DEFINITION OF POVERTY CHANGED? The latest refinements on the methodology is the third since the first official methodology was adopted in 1987. History of the official poverty estimation methodology
Year 1987 1992 2003 1 2 Refinements were made so as not to overestimate poverty Refinements were made to generate provincial poverty statistics b using i i l t t ti ti by i regional menus priced using provincial prices. Refinenements were undertaken to ensure comparability of estimates across space and over time.

· Issues on the estimation of the food threshold, poverty threshold, incidence and other measures of poverty and improvement of poverty, the relevance of official poverty statistics. Issues particularly on the comparability of poverty estimates across space and over time.

Description
- Come-up with a complete documentation of all components of the poverty methodology.
Output
-Documentation of the methodology - Reviewed/documented findings of various papers that discussed the issues being raised on the methodology. - Recommendations on the poverty estimation methodology
- Started in 2008 - Took off from the outputs of the Documentation Project - Undertaken thru the creation of 4 Small Working Groups (SWGs) - recommendations were finalized based on recommendation of TC PovStat - The Committee intended to refine methodology at the start of new administration to avoid any misconception on the objectives.

II. Highlights of the Refinements in the Methodology
Components
Existing Methodology Income-based
Proposed Methodology Income-based
Use provincial food bundles, with food items that are:
Remarks/Considerations No change
-To capture province-specific To province specific characteristics in the estimation of provincial poverty statistics -To ensure that the bundle chosen for the province is "superior" over another bundle based on preferences, that is, the former will provide the least cost but with the same level of utility -Used a national reference food bundle as a starting point to enhance consistency across space
I. ESTIMATION OF THE FOOD THRESHOLD
a. Artifice to use Use region-based food region based bundles that are:
Low-cost
-Least cost food bundle for the province as it passed the Test of Revealed Preference
-Were developed based on an indicative national food bundle

II. Highlights of the Refinements in the Methodology
Components Existing Methodology Use of the FE/TBE ratio by province urban-rural for the respective FIES year. Proposed Methodology Remarks/ Considerations
II. ESTIMATION OF THE POVERTY THRESHOLD a. FE/TBE ratio -Use the average FE/TBE ratio for 2000, 2003, 2006 and 2009 - To ensure that the parameters are fairly stable since FE/TBE ratios do not change dramatically over time (See graph on next slide) -To ensure consistency over time for at least two administrations -To ensure consistency across space -The use of a constant FE/TBE ratio has been suggested by the NSCB Technical Staff since 2003.
Press Conference on the 2009 Official Poverty Statistics LSBersales/ 08 February 2011
-To be used for 12 years
- Where the FE/TBE ratio for each FIES year is nationally determined

II. Highlights of the Refinements in the Methodology
Will back estimates be available? · Parallel estimates for 2009 using the old methodology were generated. · Likewise, back estimates for 1991, 2003 and 2006 using the , , g new methodology will be released to be able to look at trends in poverty using the same methodology, specifically for MDG monitoring · To facilitate the computation, food thresholds would be estimated based on the regional food CPI, given the manpower and resource constraints of the NSCB · E ti Estimation of th other poverty statistics (e.g., poverty ti f the th t t ti ti ( t threshold, incidence, income and poverty gap, severity of poverty) follow the same recommendations of the TC PovStat
