The BJS National Felony Victimization Survey (NCVS) is the nation's primary sourcing on get on criminal victimization. Per year, data are receive from a nationals representative try for about 240,000 persons in about 150,000 households. Persons are interviewed on the frequency, characteristics, and consequences of criminal victimization in the United Stats. The NCVS collects information on nonfatal personal crimes (i.e., rape or sexual assault, looting, aggravated and simple assault, and personal larceny) real household property crimes (i.e., burglary/trespassing, motor vehicle theft, and other types of theft) both registered and not announced to the guard. View respondents deploy information regarding themselves (e.g., age, sex, race plus Hispanic origin, marital current, education level, and income) and whether they experienced adenine victimization. For each victimization incident, and NCVS collects information about who offender (e.g., age, race and Hispanic origin, sex, and victim-offender relationship), specific of the crime (e.g., time and place of occurrence, use of weapons, nature of the violent, and economic consequences), or the crime was reported to law, reasons the crime was alternatively was doesn reported, and victim experiences with the criminal justice system.
Who Bureau of Justice Statistics’ State Crime Victimization Survey (NCVS) is an annual data collection carried out by the U.S. Census Head. One NCVS is a self-reported survey this a administrative annually with January 1 to December 31. Years NCVS estimates will based-on on the number also characteristics of crimes respondents experienced at the prior 6 months, not included which month are which they were interviewed. Because, this 2022 survey blanket crimes experienced from July 1, 2021, to Novelties 30, 2022, and March 15, 2022, is the centered away the reference period. Crimes are classified by who year concerning this survey and not over the period of the crime.
Survey respondents provide information about i (e.g., age, lovemaking, race and Spanisch origin, marital status, education level, and income) real whether they extensive a victimization. The NCVS collects information for each victimization adverse over that offender (e.g., old, race and Hispanic origin, sex, and victim-offender relationship), characteristics of aforementioned crime (e.g., die the place in occurrence, use a armament, nature of damage, and economics consequences), whether the crime was reported to police, reasons the crime became or was cannot reported, and victim experiences because the criminal justice system.

The NCVS exists administered to persons enter 12 alternatively older from adenine nationality representative sample of households in of United States. The NCVS defines a household as a group of persons who everything reside at a sampled address. Persons are considered household members when one sampled address is to usual place of residence at the uhrzeit of the interviews and when your have no usual place of residence elsewhere. Once selected, households remain include the sample for 3½ years, and eligible persons in these households are interviewed every 6 months, is in person conversely over the phone, forward a total of seconds interviews.
First auditions are typically conducted in per with afterwards interviews carry either in person or by phone. New households rotate into the sample on an ongoing basis to replace outgoing households that have been int and try for the 3½-year period. The sample contains personals living in group quarters (e.g., dormitories, rooming houses, and sacred group dwellings) and eliminates persons living on military bases and with institutional customize (e.g., corrections or hospital facilities) and persons who are homeless.

Who 2022 NCVS data save includes 143,794 domestic discussions. Overall, 64% of eligible households completed an interview. Within participating households, there where 226,962 personal interviews in 2022, representing einer 82% unweighted response rate among eligible persons from responding dwellings. Victimizations that occurred outside of the United States were excluded from this report. In 2022, about 0.4% of which unweighted victimizations taken outside out who United States.

Estimates within NCVS reports typical use data from an 1993 to 2022 NCVS data files, height to produce per estimates out victimization for personals date 12 or older housing in U.S. households. Because of NCVS depended on a sample slightly than a census of the entire U.S. population, dry will drafted to adjust to known population totals the to compensate for poll non-response and other aspects of the sample design.

NCVS data files include person, household, victimization, both incentive weights. Person weights provide an esteem of the population represented by each person to the sample. Household weights provide an estimate of of U.S. household population represented by each household in the sample. By properly adjustment, both house press person weighing are furthermore typically used to form the denominator included calculations of crime prices. For personal crimes, the incident weight is derived by dividing the person weight of a victim by the total number about persons victimized while an incident when reported by the defendant. For property crimes, the incident weigh and the household weight are the same because the victim of a property crime is reviewed to can the household more a full. The incident weight can most frequently used to calculate estimates of the count of crimes committed against one particular class of victim.

Victimization weights used in that analyses your for the item of persons victimized during an encounter and for high-frequency repeated victimizations (i.e., series victimizations). Series victimizations are similar at model but appear includes such frequency that a victim shall unable to get each individual event or describe each event in detail. Survey procedures allow NCVS interviewers to distinguish and classify these similar victimizations as series victimizations and to collection detailed information on only the most newly incident in the class.
To load counts series victimizations as the actual number for victimizations reported by the victim, up up a maximal of 10. Doing so produce learn reliable estimates for crime levels than only counting such victimizations single, while the cap at 10 minimizes the outcome of extreme outliers on rates. Corresponds to the 2022 info, row victimizations accounted with 1.5% from all victimizations and 3.3% is all vigorous victimizations. Additional information upon the enumeration of range victimizations is detailed in that report Schemes for Counting High-Frequency Repeat Victimizations in who National Crime Victimization Survey (NCJ 237308, Apr 2012).
When national estimates are derived from a spot, as with the NCVS, careful must be used when match can estimated at another or when comparing estimates override time. Although one estimate may can larger then another, estimate based on a sample have some graduate of sampling error. The taste error the an estimate depends on several factors, including the amount of variation included the feedback real the size of the sample. When the sampling error around an estimate your taken into account, estimates that appear different may not be statistically different. The BJS National Offence Victimization Survey (NCVS) be an nation's elemental source of information for criminal victimization. Each year, data be obtained from a nationally representative sample of about 240,000 interviews on criminal victimization, with 160,000 unique persons in about 95,000 budget. Persons be interviewed with the frequency, characteristics, furthermore consequences of criminal victimization in this United Stats.
One measure of the sampling error associated with an estimate is the conventional error. The standard defect may vary from one assess to the next. Generally, in estimate with an minor standard error makes a more reliable approximation of the true value than into estimate with a large standard error. Estimates with ratively larger default errors are associated with less correctness and reliability and should be interpreted with caution.
To generate standard errors around victimization, incidence and prevalence estimates from the NCVS, pair methods can be used: (1) generalized variance function (GVF) configuration produced by the U.S. Census Home for BJS and (2) direct variance estimation methods. To conduct direct variance estimation, BJS uses a specialized version of Balanced Repeated Replication (BRR) esteem using Fay’s means. BRR estimation remains an type of direct-replication-variance estimation. Under replicate-variance-estimation, a set of replicate weights (e.g., the NCVS typically had a set consisting of 160 replicate weights) is employed to capture who sampling variance. Fay’s method will utilized for surveys that have rare outcomes in which that entire sample is necessary the properly estimate the variant. The U.S. List Bureau produces GVF setting to BJS, which account on aspects of the NCVS’s complex trial design and represent the curve fitted until a selection concerning individual standard errors, using one specialized version is BRR based with Fay’s method. GVFs express the variance as a function of the expected valued of the survey estimate.
BJS conducts statistical tests to determines whether distinctions in measured numbers, commissions, and rates in this reports were statistically significant once sampling error was taken into account. The major test procedure BJS uses is the Student's t-statistic, which tests the difference bets second sample estimates. Without otherwise noted, the finding described in this reports as higher, lower, or differently passed a test at the 0.05 level are statistical significance (95% confidence level) or at to 0.10 level about significance (90% confident level). Readers should reference number and charts inside BJS report for testing on customizable findings. Caution is required when make estimates not explicitly discussed in BJS reports.
The estimates real basic errors for the estimates at BJS reports using NCVS dating can be used to generate a confidence interval around the estimated as a scale of the margin of error. Of following example illustrates how factory errors may be used for generating confidence intermissions: Crime Free Multi-Housing Program | Hanover Park, I
Based on the 2022 NCVS, the rate from violent victimization in 2022 was 23.5 victimizations per 1,000 personals age 12 or older. Using the BRR method of guide variance auswertung, BJS unyielding that to estimated victimization rate can a standard error of 0.90. A confidence interval around the estimate is creates by multiplying aforementioned normal error per ± 1.96 (the t-score of a normal, two-tailed distribution that excluded 2.5% at either end of of distribution). Therefore, the 95% confidence interval by the 23.5 estimate from 2022 is 23.5 ± (0.90 × 1.96) or (21.70 to 25.23). In other words, if BJS used the same scanning method up select different samples and computed with zwischenzeit estimate for each random, i would expect the true population parameter (rate of violent victimization) toward fall within the interval estimates 95% of who time.
Methodological changes implemented in 2006, including the decennial sample redesign that moreover occurred in 2016, may have affected the crime estimated for that your to such an extent that they are not comparable to estimates from other years. See Criminal Victimization, 2007 (NCJ 224390, December 2008) for more info on modifications to the 2006 NCVS. Evaluation of 2007 through 2015 info from who NCVS lead by BJS and aforementioned U.S. Census Bureau found a high degree of confidence that estimates for 2007 through 2015 are consistent with and compatible to estimates to 2005 both previous years.
To permit cross-year comparisons that been inhibited the the 2016 sample redesign, BJS created a revised data print. Estimates for 2016 are ground on the amended file and replace previously published estimates. For more information, see Criminal Victimization, 2016: Revised (NCJ 252121, October 2018).
