INTRODUCTION
The data used for this supplement includes written premiums and exposures for calendar years
2017-2021 for the combined voluntary and residual market. Earned and incurred loss data for
calendar/accident years 2018-2020 cannot be collected until spring of 2023 and will not be included in
this supplement. The earned and incurred loss data will be included in the full 2020/2021 Auto
Database report that will be released later this year.
The purpose of the supplement is to release written premium data and exposures on a faster timeline
than the full Auto Database report allows. The tables in this supplement, Tables 1 through Tables 5, will
be included in the full report.
Data contained in this supplement may differ from data contained in reports from previous years, as the
statistical agents periodically obtain updated information from insurers.
The insurance data was obtained from the following statistical agents: American Association of
Insurance Services (AAIS); Insurance Services Office (ISO); National Independent Statistical Service
(NISS); Independent Statistical Service, Inc. (ISS), Massachusetts Commonwealth Automobile Reinsurers
(M-CAR); and Maryland Auto Insurance Fund (MAIF). Data was also obtained from the California
Department of Insurance and the Texas Department of Insurance. The assistance of these organizations
in developing this report is greatly appreciated. There may be some data from other small statistical
agencies that are not included.
The tables in this report were prepared under the direction of the Casualty Actuarial and Statistical (C)
Task Force. Suggestions about how this database might be further improved are welcome. Questions may
be referred to Justin Cox, Data Analyst II, [email protected].

Terms and Calculations
Below are definitions of terms and calculations used in this report. Formulas will vary depending on the
application, so readers should note the exact methods used in this report. For example, Average Premium may
be defined as Written Premiums / Written Exposures instead of Earned Premiums / Earned Exposures.
Terms
Premium: The dollar amount paid for an insurance
policy.
Exposure: A finite unit of risk related to a specific
insurance coverage. In this report, exposures are
expressed as car-years. One car-year is the risk
associated with insuring one car for one year.
Written Premiums: The total premium amount of
all policies issued during a given time period.
Written Exposures: The total number of exposures,
in car-years, of all policies issued during a given
time period.
Example 1: An auto policy insuring two cars for six
months is issued on 9/28/2008, effective
10/1/2008. The cost of the policy is $600. The
policyholders decide to change insurers in early
2009 and cancel the policy effective 1/31/2009.
The written exposure for this policy is 2 cars × 1/2
year = 1 car-year and is included in calendar year
2008 exposures because the policy was issued in
2008. The written premium is $600 (cost of the
policy), and is included in calendar year 2008
premiums.

2017–2021 State Average Expenditures and
Average Premiums for Personal Automobile Insurance
Voluntary and Residual Market Business Combined
This section provides state average expenditures
and state average annual premium per insured
vehicle, for private passenger automobile insurance
for the years 2017–2021. These statistics measure
the relative cost of automobile insurance to
consumers in each state.
Results are included for bodily injury and property
damage liability (including no-fault), collision, and
comprehensive coverages—the basic components
of a personal auto insurance policy.
Average expenditure per insured vehicle is the total
written premium for liability, collision, and
comprehensive coverages divided by the liability
written car-years
1
(exposures). This assumes that all
insured vehicles carry liability coverage but do not
necessarily carry the physical damage coverages
(i.e., collision and/or comprehensive). The average
expenditure is an estimate of what consumers in
the state spent, on average, for auto insurance. In
2021, the countrywide average expenditure was
$1,062 an increase of 1.46% over the previous year.
The median state average expenditure was $926.
The state combined average premium per insured
vehicle, on the other hand, is calculated by
summing
1
A written car-year is equal to 365 days of insurance
coverage for a single vehicle and is the standard measure
of exposure for automobile insurance.
the average premiums for the three coverages. The
result is the average cost of an auto insurance
policy in the state that contains all three coverages
(i.e., liability, comprehensive, and collision). The
countrywide combined average premium increased
1.18% in 2021, to $1,189 over the prior year. The
median state combined average premium was
$1,068.
Aggregate written premiums and aggregate written
exposures are used in calculations with no
distinction as to policyholder classifications, vehicle
characteristics, or the selection of specific limits or
deductibles, all of which significantly impact the
cost of coverage. Nor do the results consider
differences in state auto and tort laws, rate filing
laws, traffic conditions, or other demographics.
CAUTION: Because of these differences, direct
comparisons between state results should be
treated with a high degree of caution.
Tables 1A–1C show the states’ 2017–2021 written
premiums, written exposures, and average
premiums for liability insurance. Tables 2A–2C and
Tables 3A–3C show the same for collision and
comprehensive insurance, respectively. State
average expenditures are provided in Table 4, and
state combined average premiums are displayed in
Table 5.

Factors that Affect State Average Expenditures and
Average Premiums
Many factors affect the state-to-state differences in
average expenditures and premiums for automobile
insurance. Some important factors include:
Underwriting and loss adjustment expense
Types of coverages purchased
Relative amounts of coverages purchased
Use of telematics
Weather
Driving locations
Accident rates
Traffic density
Vehicle theft rates
Auto repair costs
Population density
Medical and legal costs
Per capita disposable income
Rate and form filing laws
Liability insurance requirements
Auto laws (seat belt, speed limits, etc.)
Insurance rates are developed based primarily on
the insurer’s cost of paying claims. Certain broad
characteristics of a state contribute to the
frequency and severity of auto claims and insurer
loss costs in
that state. Many of these cost factors can influence
insurance prices, not only between states, but also
between communities and neighborhoods—making
price comparison between states and within a state
extremely complex.
It is reasonable to consider that the “general
economic conditions” in a state may affect the price
of auto insurance, but no direct measure of this
characteristic exists. There are measurable variables
that can be used as imperfect substitutes for these
general conditions to approximate their influence
on auto insurance price.
Three variables—urban population, miles driven per
number of highway miles, and disposable income
per capitaare correlated with the state auto
insurance premiums. Graphs on the following pages
show these variables for each state. The graphs
indicate that high-premium states tend to also be
highly urban, with higher wage and price levels, and
greater traffic density.

Data Source
Written premium and written exposure data
were obtained from AAIS, ISO, ISS, NISS, the
California Department of Insurance, the Texas
Department of Insurance, MAIF and the M-CAR.
Dividends to Policyholders
The written premiums for this report do not
include adjustments for dividends to
policyholders. The actual amount paid by
policyholders with participating policies for auto
insurance will be affected by dividends paid.
Historical Data Adjustment
Written premium and exposure data are for
2021—the most up-to-date information
reported as of year-end 2022. Data for prior
years were also adjusted to reflect the most
current information for each year. Therefore,
historical averages in this report might not
match those published in prior reports.

2017-2021 State Average Expenditures and Combined
Average Premiums for Personal Automobile Insurance
Additional State Information
California
The 2020 and 2021 California auto insurance data in
these tables is preliminary. The California
Department of Insurance performs a rigorous set of
tests on the data each year to ensure accuracy. The
tests are not completed until after the publication
of this report. Any adjustments to California data,
based on these tests, will appear in the next edition
of this report.
District of Columbia
The District of Columbia is entirely urban. As such,
results are not directly comparable to states with
rural areas.
Illinois
To obtain more geographically specific data, contact
the Illinois Department of Insurance.
Massachusetts
Data for Massachusetts reflects Safe Driver Plan
credits and surcharges for 2017-2021.
Maryland
Maryland Automobile Insurance Fund (MAIF) data
are included. The statutory purpose of MAIF’s
insured program is to provide auto insurance
policies to those eligible Maryland residents unable
to obtain insurance in the private market. Net
premium income and investment income from
these policies is available for the payment of claims
and MAIF’s administrative expenses. MAIF receives
no state general fund appropriations, and the debts
or obligations of MAIF are not deemed in any
manner to be a department of the state or a pledge
of its credit. MAIF is not structured as a residual
market mechanism. Instead, it is the insurer of last
resort for Maryland residents. See Section 20 of the
Insurance Article of the Maryland Ann. Code for
more details.
New Jersey
New Jersey is predominately urban. Results are not
directly comparable to states with large rural areas.
Historically, New Jersey has paid two to four times
the national average in dividends to policyholders,
and, at times, this has been as high as six times the
national average, which would reduce the average
expenditure and combined average premium for
New Jersey consumers if dividends were included in
premium.
Ohio
Minimum limits apply to mandatory financial
responsibility, which can be satisfied through means
other than insurance. Note policies issued or
renewed prior to December 22, 2013 had the limits
of 12.5/25/7.5. Financial Limits as of December 22,
2013 are 25/50/25.
Rhode Island
Rhode Island is predominately urban. Results are
not directly comparable to states with large rural
areas
Texas
The Texas Department of Insurance collects vehicle
and policies-in-force information at the end of each
calendar quarter for voluntary bodily injury liability,
involuntary (residual) bodily injury liability and
collision coverages. The average number of vehicles
reported for policies in force is used as
an approximation for written exposures.
Comprehensive exposures are estimated based
on the ratio of comprehensive to collision car years
for the years of 2018 to 2020. The data to estimate
this ratio only includes 70 percent of the
private passenger automobile market. That
ratio is approximately 0.99. The
estimate of comprehensive car-years
affects combined average premium, but the
estimate does not affect the calculation of the
average expenditure because only liability car-
years are used for that calculation.

The National Association of Insurance
Commissioners (NAIC) is the U.S.
standard-setting and regulatory support
organization created and governed by
the chief insurance regulators from the 50
states, the District of Columbia and five
U.S. territories. Through the NAIC, state
insurance regulators establish standards
and best practices, conduct peer review,
and coordinate their regulatory oversight.
NAIC staff supports these efforts and
represents the collective views of state
regulators domestically and internationally.
NAIC members, together with the central
resources of the NAIC, form the national
system of state-based insurance regulation
in the U.S.
