1. Value of Production Index (VaPI)

The seasonally adjusted VaPI for total manufacturing increased by 0.4 percent in October 2024. In September 2024, a 4.4 percent month-on-month decrement was observed. (Figure 1a, and Tables A and 1)

Likewise, the seasonally adjusted VaPI for food manufacturing recorded slower monthly increment in October 2024 at a monthly rate of 2.5 percent from the 3.2 percent monthly increase observed in September 2024. (Figure 1b, and Tables A and 1)

Furthermore, the seasonally adjusted VaPI of industry divisions other than the manufacture of food are shown in Table 1a.
 

2. Volume of Production Index (VoPI)

The monthly rate of the seasonally adjusted VoPI for total manufacturing recorded a slower month-on-month decrease of 0.4 percent in October 2024. In September 2024, a 3.6 percent month-on-month decrement was observed. (Figure 2a, and Tables A and 2)

On the other hand, the monthly rate of the seasonally adjusted VoPI for food manufacturing recorded a faster monthly increase of 4.1 percent this month from its monthly increment of 1.3 percent in September 2024. (Figure 2b, and Tables A and 2)
In addition, the seasonally adjusted VoPI of industry divisions other than the manufacture of food are shown in Table 2a.
 

3. Value of Net Sales Index (VaNSI)

In October 2024, the monthly rate of the seasonally adjusted VaNSI for total manufacturing slowly decreased to 0.8 percent from the 4.9 percent month-on-month decrement in September 2024. (Figure 3a, and Tables A and 3)

In contrast, a monthly increase of 3.5 percent was observed in the seasonally adjusted VaNSI for food manufacturing during the month. In September 2024, a month-on-month decline of 2.7 percent was recorded. (Figure 3b, and Tables A and 3)

Furthermore, the seasonally adjusted VaNSI of industry divisions other than the manufacture of food are shown in Table 3a.
 

4. Volume of Net Sales Index (VoNSI)

Month-on-month, the seasonally adjusted VoNSI for total manufacturing recorded a slower decrease of 1.9 percent in October 2024 from a 3.5 percent monthly drop observed in September 2024. (Figure 4a, and Tables A and 4)

On the other hand, the monthly rate of the seasonally adjusted VoNSI for food manufacturing increased by 3.7 percent in October 2024. In September 2024, a 3.4 percent month-on-month decrement was observed. (Figure 4b, and Tables A and 4)

Moreover, the seasonally adjusted VoNSI of industry divisions other than the manufacture of food are shown in Table 4a.

Technical Notes

The Monthly Integrated Survey of Selected Industries (MISSI) generates the original series of the Value of Production Index (VaPI), Volume of Production Index (VoPI), Value of Net Sales Index (VaNSI), and Volume of Net Sales Index (VoNSI). These indices provide information on the performance of growth-oriented industries in the manufacturing sector.

This special release features the seasonally adjusted VaPI, VoPI, VaNSI, and VoNSI using X-13 Auto-Regressive Integrated Moving Average (ARIMA) of JDemetra+. The seasonally adjusted series show the trend of value and volume of production and net sales of the manufacturing sector without the effects of seasonal factors.

The decomposition model chosen for the seasonal adjustment for each index is shown below.
