   ON SUGGESTION FOB REHEARING EN BANC

Before KING, EMILIO M. GARZA and DeMOSS, Circuit Judges.

EMILIO M. GARZA, Circuit Judge:

Treating the Suggestion for Rehearing En Bane as a Petition for Panel Rehearing, the Petition for Panel Rehearing is DENIED. No member of the panel nor Judge in regular active service of the Court having requested that the Court be polled on rehearing en banc (FRAP and Local Rule 35), the Suggestion for Rehearing En Banc is DENIED. However, in the interest of clarity, we withdraw our prior opinion, Houston v. Lafayette County, 51 F.3d 547 (5th Cir.1995), and substitute the following:

Residents of Lafayette County, Mississippi, appeal from the district court’s dismissal of their vote dilution challenge, under § 2 of the Voting Rights Act, 42 U.S.C. § 1973 (1988), to the redistrieting plan for county supervisor elections as submitted by the County to the United States Department of Justice for preelearance. The district court found that the plaintiff residents had failed to prove that the black population was geographically compact, that black voters exhibited political cohesion, and that white voters voted in bloc to defeat minority candidates. We vacate the district court’s judgment and remand for clarification.

I

County supervisors in Lafayette County are elected from five single-member election districts. Black residents constitute approximately one-quarter of the voting-age population and currently reside throughout the five districts. No black resident has ever been elected to the office of county supervisor. Black residents have been elected to sub-county positions such as constable and board of education member.

At trial, plaintiff residents used expert testimony and reports to prove their vote-dilution case. Plaintiffs’ expert, Victoria Cari-das, testified that black residents in Lafayette County could be placed in a majority-minority district, that is, a district where minority residents constituted a majority of the eligible voters. To demonstrate the feasibility of such placement, she submitted two alternative plans that would achieve a 54-56% black voting-age majority in one district.

Plaintiffs’ expert Dr. Allan Liehtman testified that black residents of Lafayette County exhibit political cohesion and that white residents of Lafayette County vote as a bloc to defeat minority candidates. In support of these conclusions, Dr. Liehtman testified that he used two statistical methods to analyze Lafayette County election data: bivariate ecological regression and extreme case analysis. Dr. Liehtman analyzed fourteen primary elections using ecological regression and five primary elections using extreme case analysis.

The County’s expert, Dr. Ronald Weber, also performed ecological regression and extreme ease analysis on Lafayette County election data, although he did not analyze the same elections as Dr. Liehtman had. Based on his analysis, Dr. Weber concluded that racial polarization — that is, that black residents vote for black candidates and white residents vote for white candidates — does not occur in Lafayette County.

The district court found that the plaintiff residents had not shown that black residents were sufficiently geographically compact to allow formation of a majority-minority district. The court also found that black residents did not exhibit political cohesion and that white residents did not vote as a bloc to defeat minority candidates. Alternatively, the district court found that, even if the plaintiff residents had proved geographical compactness, black political cohesion, and white bloc voting, they had failed nonetheless to prove that the totality of the circumstances showed that the County’s plan diluted minority voting strength. Plaintiff residents appeal the district court’s decision, challenging each of the above findings.

Section 2 of the Voting Rights Act provides that: “No voting qualification or prerequisite to voting or standard, practice, or procedure shall be imposed or applied by any State or political subdivision in a manner which results in a denial or abridgement of the right of any citizen of the United States to vote on account of race or color....” 42 U.S.C. § 1973; see also Thornburg v. Gingles, 478 U.S. 30, 47, 106 S.Ct. 2752, 2764, 92 L.Ed.2d 25 (1986) (“The essence of a § 2 claim is that a certain electoral law, practice, or structure interacts with social and historical conditions to cause an inequality in the opportunities enjoyed by black and white voters to elect their preferred representatives.”).

In order to prove a § 2 violation, a plaintiff must demonstrate three preconditions:

First, the minority group must be able to demonstrate that it is sufficiently large and geographically compact to constitute a majority in a single-member district_ Second, the minority group must be able to show that it is politically cohesive.... Third, the minority group must be able to demonstrate that the white majority votes sufficiently as a bloc to enable it — in the absence of special circumstances, such as the minority candidate running unopposed ... — usually to defeat the minority’s preferred candidate.

Gingles, 478 U.S. at 50-51, 106 S.Ct. at 2766-67. Although Gingles concerned at-large election districts, these preconditions also apply to challenges to single-member district-ing schemes. Growe v. Emison, — U.S. -, -, 113 S.Ct. 1075, 1084, 122 L.Ed.2d 388 (1993) (extending Gingles preconditions to single-member district cases). If a plaintiff demonstrates the Gingles preconditions, the district court determines whether, under the totality of the circumstances, the plaintiff has proven the existence of vote dilution under the challenged plan. In doing so, the district court applies factors identified by the Senate Judiciary Committee Report accompanying the 1982 amendments to § 2. Gingles, 478 U.S. at 36-37, 106 S.Ct. at 2759.

We review the district court’s findings with respect to the Gingles preconditions and the totality of the circumstances factors for clear error. See Westwego Citizens for Better Government v. City of Westwego, 946 F.2d 1109, 1118 (5th Cir.1991) (Westwego III) (reviewing findings in § 2 case for clear error); Campos v. City of Baytown, 840 F.2d 1240, 1243 (5th Cir.1988) (same), cert. denied, 492 U.S. 905, 109 S.Ct. 3213, 106 L.Ed.2d 564 (1989). “[A] finding is ‘clearly erroneous’ when although there is evidence to support it, the reviewing court on the entire evidence is left with the definite and firm conviction that a mistake has been made.” Anderson v. City of Bessemer City, 470 U.S. 564, 573, 105 S.Ct. 1504, 1511, 84 L.Ed.2d 518 (1985) (quoting United States v. United States Gypsum Co., 333 U.S. 364, 395, 68 S.Ct. 525, 542, 92 L.Ed. 746 (1948)).

A

Plaintiff residents contend that the district court clearly erred in concluding that the black population of Lafayette County was not sufficiently geographically compact to allow the formation of a majority-minority district. They argue that our decision in Clark v. Calhoun County, Miss., 21 F.3d 92 (5th Cir.1994), mandates reversal.

Plaintiff residents challenge the district court’s reasoning that “[t]he potential for increased minority influence that a majority composition of blacks within one district may afford is necessarily offset by the significantly diminished power of those left behind in the overwhelmingly white supervisor districts.” We agree with the plaintiffs contention. As we stated in Clark:

[T]he district court’s suggestion that the formation of plaintiffs’ proposed district would dilute the voting strength of black citizens in the remaining districts does not support its conclusion that the black population in [the county] is not sufficiently geographically compact. Whenever a majority-black district is created to remedy a § 2 violation, the number of black voters in the other districts must necessarily be reduced. Indeed, without this phenomenon, no majority-black districts would ever be created. Because the record in this case reflects no loss of influence that is not found in every § 2 case, the district court erred in finding that the loss of influence supported its conclusion that the black population in [the county] was not sufficiently geographically compact.

Clark, 21 F.3d at 95; see also Campos, 840 F.2d at 1244 (“The fact that there are members of the minority group outside the minority district is immaterial.... Just because not all of the minorities in [the city] are in the district does not mean that Gingles’ first part is not satisfied.”). Accordingly, the district court’s reasoning cannot support its finding that the black population is not geographically compact.

In Clark, as in this case, the district court rejected the plaintiffs’ proffered districting plan as being too oddly shaped. Compactness, however, is not as narrow a standard as the district court construed it to be. “The first Gingles precondition does not require some aesthetic ideal of compactness, but simply that the black population be sufficiently compact to constitute a majority in a single-member district.” Id. at 95. Moreover, the question is not whether the plaintiff residents’ proposed district was oddly shaped, but whether the proposal demonstrated that a geographically compact district could be drawn. See id. (“[Plaintiffs’ proposed district is not cast in stone. It was simply presented to demonstrate that a majority-black district is feasible in [the] county. If a § 2 violation is found, the county will be given the first opportunity to develop a remedial plan.” (citations omitted)). Thus, although the edges of the plaintiff residents’ proposed district look ragged in places, this does not automatically mean failure to meet the first Gingles precondition.

As in Clark, the plaintiff residents’ proposed district is not nearly as “bizarre” as those rejected in Shaw v. Reno, — U.S. -, 113 S.Ct. 2816, 125 L.Ed.2d 511 (1993), criticized in Growe, — U.S. at -, 113 S.Ct. at 1085-86, or invalidated in Vera v. Richards, 861 F.Supp. 1304, 1345 (S.D.Tex.1994) (three-judge panel), appeal filed, 63 U.S.L.W. 3388 (U.S. Oct. 31, 1994). See Shaw, — U.S. at -, 113 S.Ct. at 2826 (disapproving of reapportionment plan “so highly irregular that, on its face, it rationally cannot be understood as [being] anything other than [race-based].”). Indeed, the compactness of the district in the plaintiff residents’ proposed plan resembles that of many districts considered constitutionally ae-ceptable by other courts. See, e.g., Vera, 861 F.Supp. at 1345 (approving districts the shape of which was “at least not highly irregular apart from the small racially distinct appendages”); see also Richard G. Pildes & Richard G. Niemi, Expressive Harms, “Bizarre Districts, and Voting Rights: Evaluating Election District Appearances After Shcm v. Reno, 92 Mich.L.Rev. 483, 542 fig. 2(d), 544 fig. 2(e), 545 fig. 3(a), 547 fig. 3(d) (1993) (explaining that districts of similar compactness to that proposed in this case satisfy the first Gingles precondition). Lastly, the district in the plaintiff residents’ proposed plan is not substantially less compact than districts — which the County asserts are compact — in the County’s 1982 and 1991 plans. See Defendants’ Exhibits 1(a), 1(b), 10, 16 (1982 and 1991 County redistricting maps). The district court should have focused on the size and concentration of the minority population, rather than only on the shape of the districts in the plaintiff residents’ specific proposals. Accordingly, we hold that the district court clearly erred in finding that the black population of Lafayette County was not sufficiently geographically compact, based on its articulated rationale. Accordingly, we reverse and remand to the district court for further findings on this precondition.

B

Plaintiff residents further contend that the district court clearly erred in concluding that they had failed to satisfy the second and third Gingles preconditions because voting in Lafayette County does not exhibit signs of racial polarization. The plaintiffs’ expert, Dr. Lichtman, used both bivariate ecological regression and extreme ease analysis to show black political cohesion and white bloc voting. The district court, however, viewed the plaintiff residents’ proof on these elements as limited to the extreme case analysis, stating that “[t]o determine voter preference, ... Lichtman relied on extreme case analysis.”

The district court criticized Liehtman’s analysis because Lichtman could use extreme case analysis only on 80%-plus white-majority precincts. In the district court’s view, “[wjithout containing any heavily black precincts, Plaintiffs’ analysis is incomplete: it sheds no light on and offers little proof of either black political cohesiveness or the preferred candidate of blacks.” The district court’s commentary on Lichtmaris ecological regression consists merely of a statement that such studies are “nondemonstrative of a minority vote dilution claim” and “did not encompass other factors and variables that provide further insight to voting behaviors and patterns.” The district court favored the statistics of Dr. Weber, the defendants’ expert, because he “incorporated other acceptable research methods associated with history, and the political and social sciences.”

Plaintiff residents correctly state that we vacated this district court’s similar approach in Teague v. Attala County, 17 F.3d 796 (5th Cir.1994). In Teague, the district court rejected the plaintiffs’ statistics summarily, and we vacated the judgment because the district court had neither addressed the statistical evidence nor provided this court with sufficiently particularized findings such that we could conduct a proper appellate review. “[I]n making its intensely fact-specific inquiry here, the district court ought to have discussed appellants’ statistical evidence more thoroughly because that was the principal evidence they offered and because their statistics had at least surface plausibility.” Id. at 798.

We conclude that the district court’s findings in this case suffer the same flaws as its findings in Teague. First, the district court should have considered Licht-man’s ecological regression probative of the issues of black political cohesion and white bloc voting. See Gingles, 478 U.S. at 52-53, 106 S.Ct. at 2767 (approving of use of extreme case analysis and bivariate ecological regression analysis to prove racially polarized voting). Second, the district court should not have rejected summarily the plaintiff residents’ statistics on the grounds that they “look[ed] strictly at how, rather than why, people vote the way they do.” While “evidence that divergent voting patterns are attributable to partisan affiliation or perceived interests rather than race [is] quite probative on the question of a minority group’s future success at the polls,” League of United Latin Am. Citizens v. Clements, 999 F.2d 831, 859 (5th Cir.1993), evidence that lacks such evaluation of the voters’ possible motivations still carries probative value. The statistics the plaintiff residents offered have facial plausibility, and therefore the district court should have considered them. Teague, 17 F.3d at 798.

Moreover, as in Teague, the district court’s findings are too general to allow us to conduct our appellate review. Id. at 798 (“This court is unable to discharge our appellate function in voting rights cases without more guidance by the trial court concerning its credibility choices on the welter of evidence before it.”). Although the district court may ultimately decide that the defendants’ evidence wins this battle of statistics, the district court must at the very least thoroughly discuss its choices with specific references to the evidence proffered. See Teague, 17 F.3d at 798 (remanding for further clarification because “the district court findings on the subjects of racial polarization and minority political cohesion are broad and general and not explicitly tied to the testimony, although many witnesses were called in the case”)- Accordingly, we vacate the district court’s decision and remand for clarification of the racial-polarization and bloc-voting issues.

C

Given that we remand for further findings on the second and third Gingles preconditions, we also vacate the district court’s alternative holding that the plaintiff residents did not show that, under the totality of the circumstances, the districting scheme in Lafayette County diluted minority votes. See Clark, 21 F.3d at 97 (vacating and remanding alternative holding because findings on underlying preconditions were vacated). On remand, if the district court determines that the plaintiff residents satisfy the Gingles preconditions, it should then evaluate their claim under the totality of the circumstances. See Johnson v. DeGrandy, — U.S. -, -, 114 S.Ct. 2647, 2657, 129 L.Ed.2d 775 (1994) (explaining that proof of Gingles preconditions is necessary but not sufficient to establish a § 2 violation). We note that a totality of the circumstances discussion must contain more than the analysis provided in the opinion we have reviewed here. Specifically, the district court must consider and analyze each of the Senate Report factors incorporated in Gingles. East Jefferson Coalition for Leadership & Dev. v. Parish of Jefferson, 926 F.2d 487, 491 (5th Cir.1991) (“In evaluating the totality of the circumstances, the court should consider the [Senate Report] factors listed.... ”); see also supra note 1 and accompanying text (explaining and enumerating Senate Report factors).

Ill

For the foregoing reasons, we VACATE the judgment of the district court with respect to the Gingles preconditions and the totality of the circumstances factors. We therefore REMAND for additional findings consistent with this opinion. 
      
      . Bivariate ecological regression generates predictions of the correlation between election results and the race of the residents voting in the election. Statisticians use the correlations to estimate the percentages of black residents’ and white residents' support for particular candidates. Extreme case analysis evaluates the actual election choices of voters in precincts whose residents are predominantly — 80-90%-plus—of one race. Both methods of analysis utilize correlation coefficients and measures of statistical significance to determine the degree of confidence with which to view the estimates and predictions produced by the methods.

      .These factors are:
      1. the extent of any history of official discrimination in the state or political subdivision that touched the right of the members of the minority group to register, to vote, or otherwise to participate in the democratic process;
      2. the extent to which voting in the elections of the state or political subdivision is racially polarized;
      3. the extent to which the state or political subdivision has used unusually large election districts, majority vote requirements, anti-single shot provisions, or other voting practices or procedures that may enhance the opportunity for discrimination against the minority group;
      4. if there is a candidate slating process, whether the members of the minority group have been denied access to that process;
      5. the extent to which members of the minority group in the state or political subdivision bear the effects of discrimination in such areas as education, employment and health, which hinder their ability to participate effectively in the political process;
      6. whether political campaigns have been characterized by overt or subtle racial appeals;
      7. the extent to which members of the minority group have been elected to public office in the jurisdiction.
      Additional factors that in some cases have had probative value as part of plaintiffs' evidence to establish a violation are: whether there is a significant lack of responsiveness on the part of elected officials to the particularized needs of the members of the minority group.
      whether the policy underlying the state or political subdivision’s use of such voting qualification, prerequisite to voting, or standard, practice or procedure is tenuous.
