OPINION OF THE COURT
Plаintiffs, current and former Monroe County Family Court Judges, challenge the constitutionality of Judiciary Law §§ 221-d and 221-e on the ground that the statutorily enacted pay disparities between the Family Court Judges of Monroe County and Judges serving in the Family Courts of Sullivan, Putnam and Suffolk Counties violate their rights to equal protection under the 14th Amendment of the Federal Cоnstitu *717 tion and article I, § 11 of the State Constitution. Because a rational basis exists for the salary disparities, we hold that the challenged provisions do not violate equal protection.
In April 1992, plaintiffs commenced this action seeking declaratory, injunctive and monetary relief against defendants Matthew T. Crosson, then Chief Administratоr of the Courts of New York, Edward Regan, then Comptroller of the State of New York, and the State of New York. Plaintiffs alleged that defendants violated their equal protеction rights under the State and Federal Constitutions because, under Judiciary Law § 221-e, the statutory salaries of Sullivan and Suffolk County Family Court Judges were higher than plaintiffs’ salaries аnd, under Judiciary Law § 221-d, the salaries of Putnam County Court Judges, who serve in a multi-bench capacity, including as Family Court Judges (see, Family Ct Act § 131 [b]), were also higher.
At trial, plaintiffs profferеd evidence seeking to demonstrate a similarity — in the functions, duties and responsibilities performed — between themselves and Judges in the other counties, and that the population and caseload per Judge were substantially either equal or greater in Monroe County than in the comparator counties. Plaintiffs also sought to establish that the average cost of single-family homes in Monroe County was greater than in Sullivan County. Defendants countered with expert testimony and statistical data showing a cost of living differential between Monroe and Suffolk Counties only and, thereafter, the defense rested.
Supreme Court (1) declared that the salary disparities between plaintiffs and the Judges sitting in Family Court in Sullivan, Suffolk and Putnam Counties lacked a rational basis and violated plaintiffs’ equal protection rights, (2) awarded plaintiffs back pay with рrejudgment interest and (3) directed defendants to raise plaintiffs’ salaries to equal those of Family Court Judges in Suffolk County.
Upon defendants’ appeal, the Appellаte Division reversed as to the Putnam and Suffolk County salary differentials
(see,
*718
sonably conceivable state of facts would support the salary disparity. With respеct to the pay disparity between plaintiffs and the Sullivan County Family Court Judges, however, the court affirmed
(see, id.).
Defendants submitted to the Appellate Division 1990 U.S. Bureau of the Census dаta from the New York State Statistical Yearbook setting forth higher median home values in Sullivan County than Monroe County, similar to Yearbook data cited by this Court in finding a rational basis for other judicial salary disparities
(see, Barr v Crosson,
We granted plaintiffs’ mоtion and the State defendants’ and Chief Administrator’s cross motions for leave to appeal from the Appellate Division order.
We agree with the Appellаte Division insofar as it declared that the salary disparities between plaintiffs and their counterparts in Putnam and Suffolk Counties are constitutional. As in
Henry v Milonas (supra,
at 269), the Putnam County Court Judges’ multiple roles give rise to “distinctions in the jurisdiction, authority, duties and caseloads of [the Putnam County Court Judges] as ‘multibench’ Judges [and] preclude a determination of true unity of judiсial interest in the compared posts and provide a rational basis for the statutory salary differentials.” In addition, plaintiffs proffered no proof that the costs of living in Monroe and Suffolk County are comparable and, thus, failed to demonstrate a “true unity of * * * judicial interest * * *
indistinguishable by separate geographic
considerations”

Weissman v Evans,
Where a governmental classifiсation is not based on an inherently suspect characteristic and does not impermissibly interfere with the exercise of a fundamental right, it need only rationally further a legitimate state interest to be upheld as

constitutional
(see, Nordlinger v Hahn,
The rational basis standard of review is “ ‘a paradigm of judicial restraint’ ”
(Port Jefferson Health Care Facility v Wing,
Indeed, courts may even hypothesize the Legislature’s motivation or possible legitimate purpose
(see, Port Jefferson Health Care Facility v Wing,
Here, the State defendants submitted 1990 U.S. Census data from the 1996 New York State Statistical Yearbook (21st rev ed) demonstrating that median home values were approximately 3% higher in Sullivan County than in Monroe County — $93,400 to $90,700. The salary of a Family Court Judge in Sullivan County has been approximately 1% higher than plaintiffs’ salaries since October 1987 and has never been more than 1.96% higher than plaintiffs’ salaries
(see,
Judiciary Law §§ 221-d, 221-e). Therefore, the data illustrating the dif
*720
ference in median home values alone may provide a rational basis for the salary disparity
(see, Henry v Milonas,
The census data from the State Statistical Yearbook, which, as noted above, we relied upon in
Barr v Crosson
(
We thus conclude that the census data is properly before us and provides a rational basis for the challenged provisions. Plaintiffs have failed to satisfy their heavy burden of proving that no reasonably conceivable state of facts supports the salary disparity. Our conclusion renders academic those portions of the parties’ appeal and cross appeals challenging the Fourth Depаrtment’s denial of prejudgment interest and determination that the back pay claims were not time-barred.
Accordingly, the order of the Appellate Division should be modified, with costs to defendants, by granting judgment declaring that the salary disparity between the Family Court Judges in Monroe County and Sullivan County is constitutional and, as so modified, affirmed.
Judges Smith, Levine, Ciparick, Rosenblatt and Graffeo concur in Per Curiam opinion; Chief Judge Kaye and Judge Wesley taking no part.
Order modified, etc.
