What does month on month and year-on-year mean? Many friends should have heard of month on month and year-on-year, but many friends don't know what month on month and year-on-year mean, so the following sihai.com Xiaobian has helped you sort out the relevant knowledge. Let's have a look
What are month on month and year on year?
Month on month ratio, which represents the change ratio of quantity in two consecutive unit cycles (such as two consecutive months). Month on month growth rate = (current period - previous period) / previous period & times; 100%。 Reflect how much the current period has increased over the previous period; The month on month development speed generally refers to the ratio between the level of the reporting period and the level of the previous period, indicating the development speed of the phenomenon phase by phase.
Generally, the year-on-year ratio is the ratio between the nth month of this year and the nth month of last year. The year-on-year development speed is mainly to eliminate the impact of seasonal changes, so as to explain the relative development speed achieved by comparing the development level of this period with that of the same period last year. For example, February of the current period is higher than February of last year, and June of the current period is higher than June of last year.
Year on year growth rate = (amount in current period - amount in the same period) / | amount in the same period | & times; 100%。
Year on year and month on month differences
The month on month development rate is the ratio of the level in the reporting period to the level in the previous period, indicating the phase by phase development rate of the phenomenon. For example, calculate the comparison between each month in a year and the previous month, that is, February vs. January, March vs. February, and April vs. March & hellip& hellip; December is better than November, indicating the degree of development month by month. For example, the analysis of the development trend of some economic phenomena during the fight against SARS shows the problem more month on month than year on year.
Anyone who has learned statistics or economic knowledge knows that statistical indicators can be divided into total indicators, relative indicators and average indicators according to their specific contents, actual functions and forms of expression. Due to different base periods, the development speed can be divided into year-on-year development speed, month on month development speed and fixed base development speed. In short, year-on-year, month on month and fixed base ratio can be expressed as percentage or multiple.
The development speed of fixed base ratio, also referred to as the total speed, generally refers to the ratio between the level of the reporting period and the level of a fixed period, indicating the overall development speed of this phenomenon in a long period of time. The year-on-year development speed generally refers to the relative development speed achieved by comparing the development level of this period with that of the same period of last year. The month on month development speed generally refers to the ratio between the level of the reporting period and the level of the previous period, indicating the development speed of the phenomenon phase by phase.
Year on year and month on month, although both reflect the change speed, the connotation is completely different due to the different base period; Generally speaking, the month on month comparison can be compared with the month on month comparison, but not the year-on-year comparison with the month on month comparison; For the same place, considering the reflection of the longitudinal development trend of time, it is often necessary to compare the year-on-year and month on month.
