What is YoY? What is Chain Ring? Don t go in if you post it!

Ring is a continuous time comparison. For example, this month and last month, this season and last quarter, this year and last year, it highlights "continuity". If there is no continuous time ratio, it is not a chain comparison. The year-on-year comparison is a partition time comparison, such as April this year and April last year.

The comparison between today and yesterday is called the ring comparison; The comparison between today and last year is called year-on-year.

May 2012 compared with April 2012, called month-on-month.

May 2012 compared with May 2011, called year-on-year.

The year-on-year comparison is compared with the same period last year, and the month-on-month comparison is compared with the previous month.

This year and the same period last year are called year-on-year, and this month and last month are called month-on-month!

What does year-on-year and month-on-month mean?

1. Year-on-year: Generally refers to the comparison of the same period of the year with the month of the same period last year to calculate the year-on-year growth of the thing. The year-on-year development rate is mainly due to the development changes of enterprises and units in the current period and the same period last year in order to put aside seasonal changes and other factors;

2. Month-on-month: Generally refers to the ratio of change in the quantity of a certain thing in two consecutive unit cycles (mostly two consecutive months). The month-on-month growth rate and the month-on-month development rate can be divided into.

Differences and connections between year-on-year and month-on-month:

1. Different base periods: Although both year-on-year and month-on-month can reflect the changes in a certain thing, the base periods used by the two are different, which leads to different changes reflected in the end;

2. Different comparison methods: year-on-year is mainly to compare the same period of a certain thing, so as to judge the change in the same period; The quarter-on-quarter comparison is mainly for continuous comparison, which may be to observe the changes in a certain quarter and make adjustments. These two different methods of comparison have their own advantages, so when analyzing the indicators of something, it is possible to combine the results of the two to conduct a comprehensive analysis;

3. Year-on-year and month-on-month are both economic indicators.

Extended Information: Formula for Calculating Year-on-Year and Month-on-Month: Year-on-year refers to the ratio of the current month to the current month of the previous year, and the calculation formula is:

This month of the previous year) This month of the previous year*100 . Month-on-month refers to the ratio of the current month to the previous month (the previous month of this month) and the previous month*100.

1.The year-on-year development rate is mainly to eliminate the impact of seasonal changes, and is used to illustrate the relative development rate achieved by comparing the development level of the current period with the development level of the same period last year. For example, February of this period is compared with February of last year, and June of this period is more than June of last year.

2.The month-on-month development rate is the ratio of the level of the reporting period to the level of the previous period, indicating the development rate of the phenomenon from period to period. If you calculate the comparison of each month in a year with the previous month, i.e., February compared to January, March to February, April to March, December to November, it shows the degree of development month by month.

Year-on-year and month-on-month, although both reflect the speed of change, due to the different base periods, the connotations they reflect are completely different; Generally speaking, the year-on-month comparison can be compared with the month-on-month comparison, but the year-on-year comparison cannot be compared with the month-on-month comparison; For the same place, considering the reflection of the longitudinal development trend in time, it is often necessary to compare the year-on-year and month-on-month comparisons.

Extended information: year-on-year development rate, generally refers to the relative development rate achieved by comparing the development level of the current period with the development level of the same period of the previous year. The development rate of the ring-to-old ratio generally refers to the ratio of the level of the reporting period to the level of the previous period, indicating the development rate of the phenomenon from period to period.

For example, if the index was 90 in May last year and 100 in May this year, then March this year will increase year-on-year.

The ** index in May this year is 100, and the ** index in June this year is, so the month-on-month growth in June this year is 0.

Year-on-year vs. month-on-month breakdown:

Anyone who has studied statistics or economic knowledge knows that statistical indicators can be divided into aggregate indicators, relative indicators and average indicators according to their specific contents, actual roles and manifestations.

Due to the 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. are expressed as percentages or multiples. The month-on-month ratio is divided into daily, weekly, monthly, and year-on-year.

Formula: QoQ growth rate = (number of current periods - number of previous periods) 100% of the previous period. reflects how much the current period has increased compared to the previous period; The month-on-month development rate generally refers to the ratio of the level of the reporting period to the level of the previous period, indicating the development rate of the phenomenon period by period.

Year-on-year growth rate = (number of current periods - number of periods) 100% of the same period.

Year-on-year and quarter-on-quarter are both technical terms that describe changes in data. Month-on-month refers to the comparison of data from two adjacent months of the year. For example, in May 2021, pork was 30 yuan a catty, and in June, pork** rose to 45 yuan a catty, we can say that this month's pork** increased by 50 month-on-month.

Calculation method: year-on-year:

Comparison with the same period in history is to compare with the same period in different years, for example, July 2005 compared with July 2004, which is called year-on-year.

Month-on-month growth rate = (number of current periods - number of previous periods) 100% of the number of previous periods. reflects how much the current period has increased compared to the previous period; The month-on-month development rate generally refers to the ratio of the level of the reporting period to the level of the previous period, indicating the development rate of the phenomenon period by period.

Year-on-year growth rate = (number of current periods - number of periods) 100% of the same period.

Year-on-year:This issue is compared with the same period

Ring Ring:This issue is compared with the previous issue

Explain in detail. 1. Year-on-year refers to the comparison at the same point in the adjacent period;

As shown in **, 13 and 14 are adjacent periods, and March 13 and March 14 are the same time points of the two adjacent periods, both of which are March, and the data comparison between these two periods is year-on-year;

So, the order volume in March '14 is 80, and the order volume in March '13 is 70, then we can write like this: the order volume in March '14 increased year-on-year in 13 years.

2. Ring comparison, it is relatively simpler, that is, the comparison of adjacent time periods, unlike the same period of time, is the comparison of points between the chain of a certain time cluster within the ring time period;

Of course, we can also compare the data for the whole of '13 with the data for the whole of '14, and this data can also be seen as a month-on-month comparison.

The difference between year-on-year and month-on-month is that the definition is different, the usage is different, the calculation formula is different, and the focus is different. Among them, year-on-year refers to the comparison between the current period and the same period, while the month-on-month comparison refers to the comparison between the current period and the previous period.

1. Different definitions: year-on-year and month-on-month use high acres to indicate the direction and degree of development and change of a certain thing in the comparative period. Among them, year-on-year refers to the comparison between the current period and the same period, while the month-on-month comparison refers to the comparison between the current period and the previous period.

2. Different usage: the month is generally used in the month and day and rarely uses the sensitivity resistance in the year, mainly because of the increase in a short period of time, but due to industry differences, such as tourism will be affected by the off-peak season.

3. The calculation formula is different: the year-on-year calculation formula is (January 2018 data, January 2017 data) and January 2017 data 100%, while the month-on-month calculation formula is (February 2018 data, January 2018 data) January 2018 data 100%.

4. Different emphasis: the month-on-month ratio will highlight the short-term trend of the data, which will be affected by seasonal and other factors; The year-on-year comparison is more focused on reflecting the long-term general trend, which also avoids the seasonal factor.
