As the new infectious disease of the coronavirus (Corona19) spread, domestic mobility, which had dropped to 58% compared to last year, recovered to 83% during Golden Week. However, due to the massive infection of Club Itaewon, the amount of movement fell to 75% again.
As a result of the analysis based on mobile big data carried out by SK Telecom and the National Statistics Office on the 15th, the total number of people who moved on Saturday, February 29 was 2.53 million cases, which is said to have fallen to 58.1. % of the same period (43.07 million cases) a year ago. This decrease in movement is the greatest during the analysis period (February 8 to May 9).
On Saturday, February 2, the amount of movement was 37.3 million, which was 96.3% from last year (3,874 million), but the amount of movement plummeted as of this day.

“The increase in the number of people affected by corona19 has reduced the amount of movement, and the biggest drop occurred on the 29th of the first weekend after the 20th,” said Won Jeong-yeon, head of statistics and statistical data.

The movement of the national population is a figure converted by the National Statistics Office at the national level based on SK Telecom’s mobile movement data, which occupies 42% of the national market share. Population movement differs from the number of people who moved because they count as a case when they stayed for more than 30 minutes in a city, county, or district other than the city, county, or district where they live.

For example, if a person living in Samseong-dong, Gangnam-gu, Seoul stayed for 1 hour in Seocho-dong, Seocho-gu, and 1 hour in Banpo-dong, Seocho-gu, the total number of movements would be 2 cases. On Saturday, the amount of movement gradually increased, and on the second day of the golden party, it was 46.3 million, recovering to 82.9% from last year (50.24 million).

However, on the 9th of next week, the number fell to 75.0% from the previous year (4454 million) with 33.4 million. This appears to be the effect of slowing down when the Itaewon Club outbreak in Seoul began to unveil on the 7th.

The result of comparing the amount of movement before the crown occurs (January 9-22) is similar. The volume of the movement decreased from February 20 to 29, and then increased in early March, and the movement increased significantly during the golden holidays (April 30 to May 30).

As a result of comparing weekend and Monday-Friday trips, the effect of Corona 19 was greatest over the weekend. In particular, on the weekend of week 13 (April 27-May 3), which was the golden party, the only amount of movement increased 2.4% from before.

This trend is analyzed because people can choose to go or not on weekends. If you have not been working from home during the Corona 19 outbreak, you must work differently from your doctor during the week, but you may not be able to travel on weekends.

Since the appearance of Corona 19, the number of women instead of men, by age, has decreased significantly in people aged 20 years or younger. It is analyzed that it is related to whether to go to work or not. Since the appearance of Corona 19, commercial areas, tourist sites, and recreational sports facilities have experienced a greater decline in movement than residential areas.

However, in the thirteenth week after the golden holidays, the amount of movement in tourist attractions and leisure sports facilities increased significantly. According to cities and provinces, the influx of population has occurred mainly in tourist areas such as Jeju, Gangwon and Busan since the appearance of Corona 19 and Daegu, where large-scale confirmers have been produced.

However, in the thirteenth week, the influx of population has increased significantly to regions other than large cities such as Jeonnam, Jeonbuk, Chuam, and Gangwon. The tourist demand seems to have increased.
