</span>National Crime Victimization Survey Resource GuideAbout NCVS
The National Crime Victimization Survey (NCVS) series, previously called the National Crime Survey (NCS), has been collecting data on personal and household victimization since 1973. An ongoing survey of a nationally representative sample of residential addresses, the NCVS is the primary source of information on the characteristics of criminal victimization and on the number and types of crimes not reported to law enforcement authorities. It provides the largest national forum for victims to describe the impact of crime and characteristics of violent offenders. Twice each year, data are obtained from a nationally representative sample of roughly 49,000 households comprising about 100,000 persons on the frequency, characteristics, and consequences of criminal victimization in the United States. The survey is administered by the U.S. Census Bureau (under the U.S. Department of Commerce) on behalf of the Bureau of Justice Statistics (under the U.S. Department of Justice).
The NCVS was designed with four primary objectives: (1) to develop detailed information about the victims and consequences of crime, (2) to estimate the number and types of crimes not reported to the police, (3) to provide uniform measures of selected types of crimes, and (4) to permit comparisons over time and types of areas. The survey categorizes crimes as "personal" or "property." Personal crimes cover rape and sexual attack, robbery, aggravated and simple assault, and purse-snatching/pocket-picking, while property crimes cover burglary, theft, motor vehicle theft, and vandalism. The data from the NCVS survey are particularly useful for calculating crime rates, both aggregated and disaggregated, and for determining changes in crime rates from year to year.

Answer:
Variance = 0.02141851
Explanation:
We first calculate the mean for the stocks
Mean = (0.1858 - 0.0558 + 0.2081) / 3
Mean = 0.3381 / 3
Mean = 0.1127
Variance = [(0.1858 - 0.1127)^2 + (- 0.0558 - 0.1127)^2 + (0.2081 - 0.1127)^2] / 3 -1
Variance = [0.0731^2 + (-0.1685^2) + 0.0954^2] / 2
Variance = 0.00534361 + 0.02839225 + 0.00910116 / 2
Variance = 0.04283702 / 2
Variance = 0.02141851
The variance of returns is 0.02141851
The development of a nationwide computerized job bank listing of all job openings would be most likely to reduce cyclical unemployment.
<h3>
What is seasonal unemployment?</h3>
- When the abilities that people in the economy have to provide and the skills that employers need from employees do not match, structural unemployment results.
<h3>What is frictional unemployment?</h3>
- The time between quitting a job voluntarily and finding another is known as the frictional unemployment period.
<h3>What is natural unemployment?</h3>
- The lowest rate of unemployment brought on by actual or voluntary economic forces is known as natural unemployment, or the natural rate of unemployment.
- The number of persons experiencing natural unemployment indicates those who are jobless as a result of the structure of the labor force, such as those who have been displaced by technology or those who lack the necessary skills to find employment.
<h3>What is cyclical unemployment?</h3>
- The portion of overall unemployment that is specifically caused by cycles of economic expansion and contraction is known as cyclical unemployment.
- Typically, unemployment increases during economic downturns and decreases during boom times.
Therefore, the development of a nationwide computerized job bank listing of all job openings would be most likely to reduce cyclical unemployment.
