2020년 월급쟁이 월급 중위값은 240만원. (평균월급의 함정. 월평균 320만원)

by 원시 2022. 2. 21.

월급,연봉,주급 언급시, "평균"의 함정을 지적해야. 평균보다 '중간값,중위값 =Median'이 더 사실에 부합함.

 

"평균의 함정"을 아세요? 대부분 언론 보도 제목은 "월 평균"으로 나옴. 오늘자 언론도 마찬가지임 (월급쟁이 월평균 임금 320만원..4명 중 1명은 월급 150만원 미만)


(1) 평균월급이 2원. '월급 평균'과 '월급 중위값'의 차이. 아주 간단히 설명하면, 한국 총노동인구를 10명이라고 가정하고, 9명은 월급이 1원, 나머지 1명은 월급이 11원이면, 9+11= 총 20원, 이를 10으로 나누면, 평균월급은 2원임.


(2) 중위(메디안)월급은 1원.


중위값이란, 일렬로 세워놓고, 가장 가운데 있는 값을 의미.
1,1,1,1,1,1,1,1,1, 11 . 10명. 이 중 가운데 값은 1이죠?
중위값 구하는 공식이 있으니까,참고바랍니다.


-----------
중위값이 훨씬 더 민주주의적이죠?
통계청 발표 2020년 자료에도 잘 적시됨. 월평균은 320만원이지만, 중위월급은 240만원임. 그러니까 대다수가 240만원이라는 의미임.

 

 

What are Mean Median and Mode?

Mean, median and mode are all measures of central tendency in statistics. In different ways they each tell us what value in a data set is typical or representative of the data set.

The mean is the same as the average value of a data set and is found using a calculation. Add up all of the numbers and divide by the number of numbers in the data set.

The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median. If there are 2 numbers in the middle, the median is the average of those 2 numbers.

The mode is the number in a data set that occurs most frequently. Count how many times each number occurs in the data set. The mode is the number with the highest tally. It's ok if there is more than one mode. And if all numbers occur the same number of times there is no mode.

How to Find the Mean

  1. Add up all data values to get the sum
  2. Count the number of values in your data set
  3. Divide the sum by the count

The mean is the same as the average value in a data set.

Mean Formula

The mean  of a data set is the sum of all the data divided by the count n.

mean=x¯¯¯=ni=1xinmean=x¯=∑i=1nxin

How to Find the Median

The median x˜x~ is the data value separating the upper half of a data set from the lower half.

  • Arrange data values from lowest to highest value
  • The median is the data value in the middle of the set
  • If there are 2 data values in the middle the median is the mean of those 2 values.

Median Example

For the data set 1, 1, 2, 5, 6, 6, 9 the median is 5.

For the data set 1, 1, 2, 6, 6, 9 the median is 4. Take the mean of 2 and 6 or, (2+6)/2 = 4.

Median Formula

Ordering a data set x1 ≤ x2 ≤ x3 ≤ ... ≤ xn from lowest to highest value, the median x˜x~ is the data point separating the upper half of the data values from the lower half.

If the size of the data set n is odd the median is the value at position p where

 

p=n+12p=n+12
x˜=xpx~=xp

If n is even the median is the average of the values at positions p and p + 1 where

 

p=n2p=n2
x˜=xp+xp+12x~=xp+xp+12

How to Find the Mode

Mode is the value or values in the data set that occur most frequently.

For the data set 1, 1, 2, 5, 6, 6, 9 the mode is 1 and also 6.

Interquartile Range

IQR = Q3 - Q1

Outliers

Potential Outliers are values that lie above the Upper Fence or below the Lower Fence of the sample set.
Upper Fence = Q3 + 1.5 × Interquartile Range
Lower Fence = Q1 − 1.5 × Interquartile Range

2020년 조사 기준 대기업 월급, 중소기업의 2배..남성 소득, 여성의 1.5배
숙박음식업 근로자 소득 최하위..소득 1위는 금융보험업


(세종=연합뉴스) 곽민서 기자 = 2020년 우리나라 '월급쟁이'들은 한 달에 평균 320만원의 임금을 받은 것으로 집계됐다.
임금근로자 4명 중 1명의 월급은 150만원에도 미치지 못했고, 중소기업 근로자의 한 달 급여는 대기업의 절반 수준에 그쳤다.


임금근로자 월평균 보수 320만원…1년새 3.6%↑


21일 통계청이 발표한 '2020년 임금근로 일자리 소득(보수) 결과'에 따르면 지난 2020년 12월 당시 임금근로 일자리에 종사한 근로자의 월평균 소득은 320만원으로, 1년 전보다 3.6%(11만원) 증가했다.


전체 임금근로자 소득의 중간값을 나타내는 중위소득도 242만원으로 1년 새 3.5%(8만원) 늘었다.
소득 구간별로 보면 월평균 소득이 150만∼250만원 미만인 근로자가 27.9%로 가장 많았다.


월평균 소득이 85만원 미만인 근로자는 13.9%, 85만∼150만원 미만인 근로자는 10.2%로 각각 집계됐다.
임금근로자 4명 중 1명(24.1%)은 150만원에 못 미치는 월급을 받은 것이다.


월평균 소득이 중위소득의 50% 미만인 저임금 근로자는 19.9%였다.
반면 월평균 소득이 중위소득의 150% 이상인 고임금 근로자는 29.4%를 차지했다.


기업 규모별·성별 임금격차 여전…중기 월급은 대기업 절반 수준
기업 규모별로는 대기업 근로자의 월평균 소득이 529만원으로 가장 높았다.
중소기업 근로자의 경우 월평균 소득이 259만원으로 대기업의 절반 수준에 그쳤다.


이러한 임금 차이는 근로자 연령대가 올라갈수록 더욱 벌어졌는데, 50대에서는 대기업 평균소득(687만원)이 중소기업(280만원)의 약 2.5배에 달했다.


남성이 여성보다 높은 임금을 받는 성별 임금 격차도 여전한 것으로 나타났다.


남성 근로자의 월평균 소득은 371만원으로 여성(247만원)의 약 1.5배에 달했고, 월평균 소득이 150만원 미만인 근로자 비중도 여성(28.9%)이 남성(20.6%)을 웃돌았다.


같은 대기업에서도 남성의 월평균 소득은 599만원, 여성은 370만원으로 임금 차이가 벌어졌다.
남성과 여성의 소득 차이(남성 평균소득-여성 평균소득)는 50대(197만원)에서 가장 크게 나타났다.
성별 임금 격차는 20대가 20만원, 30대가 66만원, 40대가 154만원 등으로 역시 연령대가 올라갈수록 점점 확대되는 모습이었다.


금융·보험업 평균 소득 660만원으로 1위…주식시장 활황 영향
산업별로는 금융·보험업에 종사하는 임금근로자의 월평균 소득이 660만원으로 가장 높았다.
금융·보험업이 산업별 소득 1위를 차지한 것은 관련 통계 작성이 시작된 2016년 이래 처음이다.


이외 전기·가스·증기·공기조절공급업(657만원), 국제·외국기관(478만원) 등의 순이었다.
반면 임금근로자 소득이 가장 낮은 업종은 숙박·음식점업으로, 월평균 소득이 163만원에 그쳤다.
전년과 비교하면 공공행정(-5.9%)과 운수·창고업(-0.3%)에서 근로자 소득이 줄었다.


통계청 차진숙 행정통계과장은 "2020년 주식시장 활황의 영향으로 금융·보험업 근로자 소득이 큰 폭으로 증가했다"며 "다만 운수·창고업의 경우 코로나19의 영향으로 대형 항공사 무급 휴직이 늘어나다 보니 소득이 감소한 것으로 보인다"고 설명했다.
