The annual inflation rate of Central Luzon in October 2019 went up at 2.3 percent after it posted deceleration for the past two months (See Figure 1). Its annual rate in September 2019 was 2.1 percent while in October 2018, 4.4 percent.

Figure 1 presents the year-on-year changes of the CPI from October 2018 to October 2019.

The annual inflation rate of the region accelerated to 2.3 percent for the month of October 2019. It recorded the highest annual inflation rate among the seventeen regions of the country. Six regions posted negative annual rates in October 2019, namely Zamboanga Peninsula (1.3%), Eastern Visayas (0.7%), Davao Region (0.7%), Cagayan Valley (0.5%), Caraga (0.4%) and Central Visayas (0.1%). Meanwhile, Ilocos Region followed Central Luzon in posting the second highest inflation rate at 1.8 percent. The national inflation rate in October 2019 was posted at 0.8 percent, lower than the 0.9 percent posted in September 2019. (See Figure 2)

The acceleration in the annual inflation rate of the region can be attributed to the increase in the heavily weighted food and non-alcoholic beverages at 0.5 percent from a  0.2 percent decline in September 2019. (See Table 1)

Month-on-Month Price Situation

Technical Notes


This Special Release presents the results of the Survey of Retail Prices of Commodities and Services for the Generation of Consumer Price Index (CPI) conducted in October 2019. 


The CPI is an indicator of the change in the average retail prices of a fixed basket of goods and services commonly purchased by households for their day-to-day consumption relative to a base year.

Uses of the CPI

As an indicator, the CPI is most widely used in the calculation of the inflation rate and purchasing power of the peso. It is a major statistical series used for economic analysis and as monitoring indicator of government economic policy.

The CPI is also used as a deflator to express value series in real terms, which is, measuring the change in actual volume of transaction by removing the effects of price changes. Another major importance of the CPI is its use as basis to adjust wages in labor management contracts as well as pensions and retirement benefits. The CPI also serves as inputs in wage adjustments through the collective bargaining agreements.

Components of the CPI

  1. Base Period

This is a reference date or simply a convenient benchmark to which a continuous series of index numbers can be related. Since the CPI measures the average changes in the retail prices of a fixed basket of goods, it is necessary to compare the movement in previous years back to a reference date at which the index is taken as equal to 100.

The present series uses the 2012 as the base year. The year 2012 was chosen as the base year because it is the year when the Family Income and Expenditure Survey (FIES) was conducted. The FIES is the basis of the CPI weights.

  1. Market Basket

Market basket refers to a sample of thousands of varieties of goods purchased for consumption and services availed by the households in the country. It was selected to represent the composite price behaviour of all goods and services purchased by the consumers.

  1. Weighting System

The weighting system is a desirable system that considers the relevance of the components of the index. For the CPI, the weighting pattern uses the expenditures on various consumer items purchased by households as a proportion to total expenditures.

  1. Geographic Coverage

CPI values are computed at the national, regional, and provincial levels, and for selected cities. A separate CPI for NCR is also computed.

  1. Classification Standards

The 2012-based CPI series is the first in the series that used the 1999 United Nations Classification of the Individual Consumption According to Purpose (COICOP) in determining the commodity groupings of the items and services included in the market basket. The 2012-based CPI also follows the 2015 Philippine Standard Geographic Classification codes.

Inflation Rate

The inflation rate (IR) is the annual or monthly rate of change of the CPI in percent. It is interpreted in terms of declining purchasing power of money.
