失业率, 是指没有工作且在积极找工作的人（除了小孩，老人，不能工作者）占劳动人口总数的百分比。公式：失业率% = 失业人数 /（在业人数+失业人数）%。
Unemployment rate refers to the percentage of people who are unemployed and actively looking for work (except children, the elderly, and those who cannot work) in the total labor force. Formula: Unemployment rate% = Number of unemployed people / (number of employed people + number of unemployed people)%.
失业率是资本市场的重要指标，属滞后指标范畴。失业率增加是经济疲软的信号，可导致政府放松银根，刺激经济增长；相反失业率下降，将形成通货膨胀，使央行收紧银根，减少货币投放。
失业率是反映劳动力市场供需情况的指标，是各国宏观调控的主要目标。根据数据来源不同，又将其分为调查失业率和登记失业率，通过抽样调查获得的失业率就是调查失业率。
失业数据的月份变动可适当反映经济发展。失业率与经济增长率具有反向的对应变动关系。
失业率是反映一个国家或地区劳动力资源利用程度的核心指标，一般来讲，失业率上升意味着更多的劳动力资源不能得到有效的利用，失业者增加从而导致社会总需求下降，经济增长动力也将减弱。因此，各国政府历来都把失业率作为判断宏观经济运行状况和劳动力市场景气程度，进而出台或调整相关宏观经济政策和就业政策的重要依据。
另外，失业率数字的反面是就业数字，其中最有代表性的是非农业就业数据。非农业就业数字为失业数字中的一个项目，该项目主要统计从事农业生产以外的职位变化情形，它能反映出制造行业和服务行业的发展及其增长，数字减少便代表企业减低生产，经济步入萧条。当社会经济较快时，消费自然随之而增加，消费性以及服务性行业的职位也就增多。当非农业就业数字大幅增加时，理论上对汇率应当有利；反之则相反。因此，该数据是观察社会经济和金融发展程度和状况的一项重要指标。
Unemployment rate an important indicator of the capital market and belongs to the category of lagging indicators. An increase in unemployment rate is a signal of economic weakness, which can lead the government to loosen monetary policy and stimulate economic growth; on the contrary, a decrease in unemployment rate will form inflation, causing the central bank to tighten monetary policy and reduce money supply.
The unemployment rate is an indicator that reflects the supply and demand situation in the labor market and is the main goal of macroeconomic regulation in various countries. According to different data sources, it is divided into survey unemployment rate and registered unemployment rate. The unemployment rate obtained through sampling survey is the survey unemployment rate.
The monthly changes in unemployment data can appropriately reflect economic development. The unemployment rate and economic growth rate have an inverse corresponding change relationship.
The unemployment rate is a core indicator that reflects the degree of utilization of labor resources in a country or region. Generally speaking, an increase in unemployment rate means that more labor resources cannot be effectively utilized, and an increase in the number of unemployed people will lead to a decline in total social demand, and the driving force of economic growth will also be weakened. Therefore, governments of various countries have always used unemployment rate as an important basis for judging the operation of macroeconomics and the prosperity of labor market, and then issuing or adjusting relevant macroeconomic policies and employment policies.
In addition, the opposite of unemployment rate is employment data, among which the most representative is non-agricultural employment data. Non-agricultural employment data is one of the items in unemployment data. This item mainly counts the changes in positions outside agricultural production. It can reflect the development and growth of manufacturing and service industries. A decrease in the number means that enterprises reduce production and the economy enters a recession. When the social economy is faster, consumption will naturally increase, and the number of positions in consumer and service industries will also increase. When the non-agricultural employment figures increase significantly, it should be beneficial to the exchange rate in theory; otherwise, it is the opposite. Therefore, this data is an important indicator for observing the degree and status of social, economic and financial development.
