OPINION OF THE COURT
The issue on appeal is whether Pennsylvania Act 1935-414 § 154 violates the Privileges and Immunities Clause of the United States Constitution by requiring contractors to employ only Pennsylvania residents as laborers and mechanics on Commonwealth-funded public works projects. Because the statute’s discrimination is not “substantially justified,” we hold it is unconstitutional.
I.
On May 12, 1994, the Pennsylvania Department of Transportation accepted bids for the Potter County highway improvement construction project. A.L. Blades & Sons, a New York based highway construction contractor, was the apparent low bidder. After awarding the contract, PennDOT notified Blades that the § 154 residency requirement would be strictly enforced.
Section 154 of Pennsylvania Act 1935-414 provides:
§ 154. Resident laborers and mechanics
The specifications upon which contracts are entered into by the Commonwealth, county, municipality, or other subdivisions of the Commonwealth, for the construction, alteration, or repair of any public works shall contain the provision that laborers and mechanics employed on such public works shall have been residents of the Commonwealth for at least ninety days prior to their employment; and failure to keep and comply with such provision shall be sufficient legal reason to refuse payment of the contract price to the contractor.
Act of July 19, 1935, Pub.L. 1321, No. 414, § 1 (1935), codified at 43 Pa. Stat. Ann. § 154. This statute was enacted during the Great Depression to ensure that Pennsylvania residents, and particularly those unemployed, would be the sole beneficiaries of state funds spent on public works.
To comply with the Act, PennDOT includes in each construction contract a provision which reads:
*868 Section 107.26. This section does not apply to projects which are partially or totally financed with Federal Funds.2
a. Residence requirements. Laborers an d mechanics to be employed for work under the contract are required by Act 1935-414 to have been residents of the State for at least 90 days prior to their starting work on the contract. Failure to comply with these provisions will be sufficient reason to refuse paying the contract price.
The Potter County contract was fully financed by the Commonwealth and contained this residence provision. Nevertheless, Blades employed Jeffrey Elliot and Simon Barnes who were New York residents. In November and December 1994, PennDOT notified Blades that continued employment of nonresident workers could result in withholding contract payments and could affect its prequalification status to do future work in Pennsylvania. Following this notification, Blades fired Elliot and Barnes.
In December 1994, Blades, Elliot, and Barnes (hereinafter “Blades”) brought this action against the Pennsylvania Secretary of Transportation and other officials of Penn-DOT.
Both Blades and the Commonwealth filed motions for partial summary judgment on the Privileges and Immunities claim.
Blades’ expert, Dr. Gerald Glyde, analyzed the construction industry for 1990, 1992, and 1994, and determined the impact of the Act on Pennsylvania unemployment was quite small. Without the residency requirement, he estimated that Commonwealth residents would have lost at least 57 construction jobs in 1994 and at most 139 jobs in 1990.
Disputing this testimony, the Commonwealth asserted that unemployment in the
The Commonwealth’s expert, Dr. David Passmore, conducted a different analysis. Focusing on nonresident workers who work in Pennsylvania but remove their income to their states of residence, Passmore believed this “migration of economic benefits” caused Pennsylvania to lose a significant amount of spending, savings, and local taxes. Passmore estimated that in 1990 nonresidents working on construction projects in the Commonwealth earned and removed from Pennsylvania $513,773 in wages and salaries. Employing a ripple effect theory, Passmore testified that a single resident highway construction worker generated an additional $64,705 in Pennsylvania industrial output; $39,176 in Pennsylvania goods and services sold for personal consumption; $20,539 in Pennsylvania personal income; $34,529 in total Pennsylvania income; $71 in local Pennsylvania taxes; and one Pennsylvania job. As a consequence, Pennsylvania loses these economic benefits when it permits nonresidents to work on Commonwealth-funded construction projects. Looking at Glyde’s 139 job loss figure, Passmore estimated Pennsylvania would have foregone $8,993,995 in industrial output value; $5,445,464 in goods and services; $8,779,240 in disposable personal income; $4,799,531 in total income; $9,869 in local taxes; and 139 Pennsylvania jobs.
After Blades withdrew its state constitutional claims, the Commonwealth filed another motion for partial summary judgment on the equal protection count. The district court granted the Commonwealth summary judgment on the Privileges and Immunities claim and the equal protection claim. A.L. Blades & Sons, v. Yerusalim,
II.
We have jurisdiction over the final order of the district court under 28 U.S.C. § 1291. Our review of the district court’s grant of summary judgment is plenary. “When we review a grant of summary judgment, we apply the same test as the district court should have applied initially.” Sempier v. Johnson & Higgins,
III.
A.
The Privileges and Immunities Clause of Article IV, § 2 of the United States Constitution provides: “The citizens of each state shall be entitled to all privileges and immunities of citizens in several states.” The Clause is designed to prevent the discriminatory treatment of citizens from other states. As the Supreme Court held “ ‘[i]t was undoubtedly the object of the [Privileges and Immunities] Clause ... to place the citizens of each State upon the same footing with citizens of other States, so far as the advantages resulting from citizenship in those States are concerned.’ ” Baldwin v. Fish and Game Commission of Montana,
But this protection is not absolute. The Supreme Court has set forth a three-prong test to determine when a discriminatory act violates the Privileges and Immunities Clause. See Toomer v. Witsell,
B.
In the first instance, we must determine whether the Act “burdens one of those privileges and immunities protected by the clause.” United Bldg.,
C.
The second prong of the test is whether there is a substantial reason for the statute’s discriminatory approach beyond the mere fact that the targeted group is comprised of citizens of other states.
The Commonwealth offered two “substantial justifications” for the § 154 residency requirement— alleviating high unemployment in the Commonwealth’s construction industry and avoiding the loss of economic benefits resulting from the expenditure of Commonwealth funds on nonresident workers. The district court rejected the unemployment justification, but held the loss of economic benefits attributed to nonresident workers removing their earnings to their states of residency justified the statute’s discriminatory approach. Blades,
i.
The first inquiry is straightforward. The district court held that the unemployment theory failed the “peculiar source” prong of the substantial justification analysis. We agree.
The Commonwealth proffered no evidence why the nonresident employees constituted a “peculiar source” of the Commonwealth’s high unemployment in the construction industry. First of all, on a comparative basis, the unemployment rate for Pennsylvania’s construction industry is not high. The district court found that in comparison to neighboring states, Pennsylvania’s construction industry unemployment rate was not significantly higher. Blades,
Secondly, there is no record evidence of any difference between the nonresident construction workers and the resident construction workers, other than their states of residency. As the district court found: “No point with respect to union status or wages is raised, nor any practice or equipment employed by out-of-state construction workers which distinguishes them from Pennsylvania residents.” Blades,
The record also reflects that nonresident employees do not constitute a peculiar source, or for that matter a significant source, of unemployment in the construction industry. The Commonwealth’s expert estimated “that in 1990, 245 Pennsylvania residents would have been displaced from fully state-funded highway projects if the residency requirement of Act 1935-414 were eliminated.” Defs.’ Statement of Material Undisputed Facts, at
The Commonwealth did not demonstrate that nonresidents were a “peculiar source,” or for that matter a significant source of the unemployment evil the residency statute was intended to address.
ii.
The district court granted summary judgment for the Commonwealth holding that the migration of economic benefits theory substantially justified the discrimination found in § 154. The court found:
(1) The Commonwealth experiences an outflow of funds related to the construction industry.
(2) This outflow exists despite a residency requirement for road construction projects funded entirely by the Commonwealth.
(3) Without the residency requirement, the outflow of funds would be much more severe, and would have serious, adverse effects on the state economy in a number of ways.
(4) Out-of-state construction workers are a peculiar source of this evil because they take the money home, thereby causing the drain.
(5) By removing the residency requirement, the Commonwealth would effectively be subsidizing the outflow, since it is state funds which would be expended in the ripple effect.
(6) the effect on out-of-state workers is not more sweeping than necessary, since the requirement does not even come close to eliminating the outflow, and jobs on 85% of Pennsylvania’s road construction projects are available to out-of-state residents.
Blades,
a.
Before a court determines whether nonresidents constitute a “peculiar evil,” it first must find that the evil was one in which the “statute is aimed.” United Bldg.,
In response, the Commonwealth cites a single reference in a different passage of the legislative history which it believes establishes the legislature’s intention to curb the migration of state funds. “In the lower end of our county we have ... many residents, many taxpayers, home owners, who are out of employment and there are people coming in from Delaware and Maryland who work all week, collect their pay on Saturday, and go back down into Delaware and Maryland and spend their pay, and have their families down there while our people in Delaware County are out of work.” Legislative Journal, House, May 1, 1935 at 3034 (remarks of Mr. Turner).
As we have seen, the statute itself does not recite the purpose behind the residency requirement. But after reviewing the legislative debate, we believe unemployment and the related problem of a large number of Pennsylvanians on the “relief rolls” were the “evils” § 154 was intended to address when it was passed in 1935. Under the Supreme Court’s test, the Commonwealth was required to establish that non-Pennsylvania residents “constitute a peculiar source of the evil at which the statute is aimed.” Hicklin,
b.
If the migration of economic benefits is the evil § 154 was “aimed” to address, the Commonwealth must nonetheless establish that the nonresident construction workers, who are the targets of the discriminatory residency requirement, constitute a “peculiar source” of that migration.
In Toomer the Supreme Court refused to uphold South Carolina’s commercial shrimp fishing statute which discriminated against nonresident shrimp fishermen, in part, because the record did not demonstrate how the nonresidents’ fishing techniques harmed South Carolina more than the techniques of the South Carolina fishermen. South Carolina had passed a statute that required nonresident fishermen to pay commercial license fees one hundred times greater than the fees required from the resident fishermen. The Court held “[njothing in the record indicates that non-residents use larger boats, or different fishing methods than residents, that the cost of enforcing the laws against them is appreciably greater, or that any substantial amount of the State’s general funds is devoted to shrimp conservation.” Toomer,
If the Commonwealth’s limited evidence were sufficient to substantially justify the discrimination, then the migration of economic benefits theory would validate virtually every employment residency requirement. But the Commonwealth’s evidence is insufficient because the Privileges and Immunities Clause requires the nonresidents to be a peculiar source of the evil rather than merely a contributor to the problem.
c.
In granting summary judgment to the Commonwealth, the district court relied on United Bldg. v. Mayor,
Here, the Commonwealth failed to present any evidence proving that nonresident construction workers were a peculiar source of the migration of economic benefit problem. Because neither the unemployment or economic benefit migration justifications satisfy the Toomer test, the Commonwealth has failed to establish that Act 1935-414 § 154 is constitutional.
IV.
For the foregoing reasons we will reverse the district court’s grant of summary judgment for the Commonwealth. We will remand this matter to the district court with instruction to enter judgment for plaintiffs.

See Legislative Journal, House, May 1, 1935, at 3032 (remarks of Mr. Sowers)("[I]s it not our great problem to put those who are on the relief rolls to work?"); Id. at 3035 (remarks of Mr. McDevitt) ("Lei us spend our money on our people. That is the only point involved here; to take care of Pennsylvania’s unemployed with government money.”).
. According to PennDOT approximately fifteen percent of PennDOT highway construction projects are completely Commonwealth-funded while eight-five percent are funded totally or partially with federal funds.
. The defendants, the Pennsylvania Secretary of Transportation, the deputy Secretary for Highway Administration, the District Engineer for Engineering District 2-0, the Assistant District Engineer for Construction in District 2-0, and an Assistant Construction Engineer in District 2-0 (hereinafter "Commonwealth”) were all sued in their individual and official capacities. William Moyer and Howard Yerusalim left PennDOT after the complaint was filed. Their replacements, Michael Ryan and Bradley Mallory, were subsequently added to the suit in their official capacities.
. The Privileges and Immunities challenge may be brought on behalf of the individual plaintiffs but not A.L. Blades & Sons since it is a corporation. Western & S.L.I. Co. v. Board of Equalization,
.Glyde's figures were subject to some uncertainty because there were many factors which might affect the impact of the Act which were not quantified or included in his analysis. For example, nonresident workers who replace the resident workers on the state projects may have left federal projects to work on the state projects, thereby leaving their old positions vacant for resident workers to fill. Also, there may be retaliation from other states that implement similar residency requirements which discriminate against Pennsylvania construction workers who seek employment out-of-state.
. Passmore estimated the Commonwealth would lose 245 construction jobs if the residency requirement were lilted. Using this estimate, Pass-more calculated Pennsylvania would lose $15,-852,725 in industrial output value; $9,598,120 in goods and services produced; $15,449,700 in disposable personal income; $8,459,605 in total income; $17,395 in local tax revenues; and 245 Pennsylvania jobs.
. Blades did not bring a Commerce Clause challenge to the residency requirement. The Commerce Clause and the Privileges and Immunities clause are often raised in tandem because both "centrally define the relationship of the states to one another and delineate the treatment that one state must accord the citizens of another.” Laurence H. Tribe, American Constitutional Law § 6-1, at 401 (2d ed.1988). Moreover, both clauses are "rooted in the common purpose of protecting United States citizens from parochial, self-interested slate actions that curtail economic and political freedoms of nonresidents and inhibit the growth of a competitive national market and a unified people.” Thomas H. Day, Note, Hiring Preference Acts: Has the Supreme Court Rendered them Violations of the Privileges And Immunities Clause?, 54 Fordham L.Rev. 271, 274 (1985). But "[t]he two clauses have different aims and standards for state conduct." United Bldg. & Constr. Trades Council of Camden County and Vicinity v. Mayor and Council of the City of Camden,
. Even though Blades bears the burden of proving the Commonwealth’s residency requirement is unconstitutional, once it is shown the statute discriminates against nonresidents’ fundamental rights, the Commonwealth bears the burden of substantially justifying the discrimination. W.C.M. Window Co., Inc. v. Bernardi,
. "Peculiar” is defined as “belonging exclusively or especially] to a person or group ... tending to be characteristic of one only; Distinctive.” Webster’s Third New International Dictionary 1663 (Philip Babcock Gove ed., 1964).
. The 1990 figures were the most favorable statistics in the record for the Commonwealth. Therefore, we analyze this year to determine if the nonresidents constitute a “peculiar source” of the unemployment problem. If they do not qualify as a “peculiar source" in 1990, then the Commonwealth cannot argue the nonresidents satisfy the test for the other years where the job displacement figures were lower.
. A similar analysis was performed in 1st Westco Corp. v. School Dist. of Phila.,
.A survey of the jurisprudence reveals six state courts that held similar construction industry residency requirements were unconstitutional. Bernardi v. Leary Constr. Co., Inc.,
. The 42,433 figure was derived from averaging all of the estimated Pennsylvania Construction industry unemployment totals provided in the record (years 1990, 1992, 1994).
. Because the peculiar source component of the substantial justification test is dispositive, we do not reach the "valid independent” reason inquiry. But we note it is not clear the elimination of the migration of economic benefit problem constitutes a “valid independent” justification for the statute. In our complex national economy, discrimination against nonresidents because they choose to spend their incomes in their states of residence would appear to be the type of discrimination the Privileges and Immunities Clause was drafted to eliminate. See Piper,
. In fact, the Commonwealth’s analysis only relied on a single job displacement estimate for the year 1990. There are no other estimates provided in the Commonwealth’s evidentiary submission. But Blades’ expert provided job displacement estimates for 1990, 1992, and 1994. He assumed at most 139 jobs would be lost to Commonwealth employees in 1990, 110 in 1992, and 57 in 1994. Therefore, according to Blades’ estimates, the evil resulting from the use of nonresident construction labor has significantly diminished over the course of the 1990’s.
. The Alaskan Supreme Court found significant the failure to document, in the record, the savings generated from additional out-of-state contractors bidding on publicly funded projects. See Felton Constr. Co.,
. The ordinance required that contractors who receive city funded construction contracts "shall make every effort to employ persons residing within the City of Camden but, in no event, shall less than forty percent (40%) of the entire labor force be residents of the City of Camden.” United Bldg.,
. Because we conclude Section 154 violates the Privileges and Immunities Clause of the United States Constitution, we do not reach the equal protection challenges.
