The vote on renaming Ocean Beach Park also is included. The report hopefully can help us better understand the demographic and political changes tp.king place in our city. The analysis is based on the sociological and statistical methods routinely used in the analysis of elections-- bivariate ecological regression analysis and homogeneous precinct analysis (where available). The methodology is similar to that used in my 1994 study which analyzed elections in Miami Beach from 1983 through 1993. The 1994 study led to some rather negative personal reactions against me by a few people who did not agree with the results and their explanations. Despite those reactions, as an academician I continue to believe that knowledge has the potential to help us solve areas of conflict. I hope that this information will be useful in helping us reach areas of agreement and avoiding areas of divisiveness in our community. I beseech you to use the information in a positive manner.

Lavender, Ph.D. and Chris Girard, Ph.D. Department of Sociology and Anthropology Florida International University January 1996 On November 7, 1995, the City of Miami Beach held an election for Mayor and two Commissioners. The mayor serves a two-year term, with elections being held in November of every odd-numbered year. Six commissioners serve four-year terms, but the terms are staggered so that three commission seats are up for election every two years at the same time as the election for mayor. In November 7, 1995, there were two candidates for mayor. The incumbent mayor, retired judge Seymour Gelber, ran for reelection after serving two consecutive terms from November 1991 to November 1995. The other candidate was Andrew Delaplaine, the editor of a local small newspaper, with no previous elective experience in Miami Beach politics. The three commission seats up for election in November 1995 were the seats held by Commissioners David Pearlson, Martin Shapiro, and Susan Gottlieb. All three commissioners ran for reelection. Commissioner David Pearlson, who had served a four-year term from November 1991 to November 1995, had no opponent, and hence received another four-year term without an election. Commissioner Martin Shapiro was a six-year incumbent, having first been elected in 1989 for a two-year term, and being reelected in 1991 for a four-year term. He was opposed by Matti Bower, a local community activist with experience in civic and educational activities. Commissioner Susan Gottlieb was first elected in 1991, for a four-year term, and was opposed by Ada Llerandi, a local hotelier who served on one of the city's most important committees. The November 1995 election was the first election held after federal judge James Kehoe ruled, earlier in 1995, against a group of Hispanic plaintiffs who argued that the city's at-large elections kept Hispanics from winning because of ethnically polarized voting. A previous study by these authors indicated that ethnically polarized voting had been a common pattern in Miami Beach elections since the city had developed- a sizable Hispanic voting population in the last decade or so (Lavender and Girard, September 1994) . In the election of November 1995, none of the incumbents, but two of the challengers, were Hispanic--Ada Llerandi who challenged incumbent Commissioner Susan Gottlieb, and Matti Bower who challenged incumbent Commissioner Martin Shapiro. Hence, this study uses the same two techniques that were used in the previous study-- homogeneous precinct analysis and bivariate ecological regression analysis--to determine ethnic voting patterns for these two elections in November 1995. In addition, this study also analyses the other two issues, the mayor's race and the question of whether to change the name of Ocean Beach Park to Marjorie Stoneman Douglas Park, in order to determine whether these races exhibited ethnic voting patterns. Voters List The analyses herein are based on a listing of all individual voters in Miami Beach, coded for whether or not they voted in November 1995. Hence, these analyses are not based simply on group (precinct) level results. One slight disadvantage of using this individual data is that it takes the elections board several weeks to post on the voting roll whether or not each person voted, and by that time a few other changes have taken place--including a few people who voted in November being removed from the voting list. [The voting list is not "frozen" on the day of the election, but is changed almost daily as people or added to or removed from the voting list]. However, the number of voters "lost" from the analyses was only 35, from a listing of 34,812 to 34,777. This is a loss of only one-tenth of one percent. The "percentage of votes counted" thus might be off by about one-tenth of one percent or less. On the other hand, one advantage of using the individual listing is that the 759 voters who voted by absentee ballots are included in these analyses, and are counted in the precincts in which they live. If the original precinct data had been used, these 759 voters would be lost from the analyses because it would not be possible to put them into the correct precinct or to determine whether they were Hispanics or non-Hispanics. The loss of voters is very small (35), and the gain (759) is much greater than the loss because we are able to use individual instead of group data in determining ethnic status. In addition, and perhaps more importantly, the individual data allows us to obtain results for ethnic subgroups, age subgroups, and a number of other demographic subgroups, results that are not possible from precinct data. Definitions Before January 1995, voters gave their place of birth when they registered as voters. Dade County election officials then gave Hispanic [Latin] registration figures based on foreign-born voters only, those voters born in a Spanish-speaking country or Puerto Rico. Voters not born in a Spanish-speaking country or Puerto Rico were counted as "non-Latin," regardless of their Spanish heritage or identity. In our September 1994 study, we estimated the number of United States-born Hispanic voters (voters born outside a Spanish-speaking country, about 95% of whom were born in the United States) by using a Distinctive Hispanic Names Technique. These two groups are combined to estimate the total number of Hispanic voters. 2 Beginning in January 1995, the voter registration process no longer asked place of birth, but asked voters to indicate their ethnic identity. Hence, the total number of Hispanic voters for the November 1995 election consists of a combination of foreign-born and estimated United States-born (using the Distinctive Hispanic Names Technique) for those registered prior to January 1995, plus those who registered during 1995 and identified their ethnicity as Hispanic. The total of 12,945 Hispanic voters consists of 9,626 foreign-born, 2,077 estimated United States-born, and 1,242 self- identified as Hispanic (first registered in 1995). In order to compare voter turnouts for different ethnic groups in Miami Beach, a Distinctive Jewish Names Technique is used to obtain a sample of Jewish voters, and a list of Distinctive Anglo Names is used to obtain a sample of Anglo (non-Hispanic, non-Jewish, non-black) voters. These two listings give samples, although the Distinctive Jewish Names Technique has been used frequently for fifty years to predict Jewish population sizes. Estimated Ethnic Voter Registration Numbers Using the techniques described above, the following are estimates of the ethnic breakdown of voters by percentages for the last few years, including the November 7th, 1995, election (Lavender, 1991: 11; Lavender, 1993, 10): Feb. 1991 Jan. 1993 Nov. 1995 Total Number of Voters 37,014 38,552 34,777* Hispanic Number 10,334 11,954 12,945 Non-Hispanic Number 26,680 26,598 21,832 Jewish Number 19,687 17,900 13 , 142 "Other" Number** 7,797 9,457 9,290 Percent Hispanic 27.9 31.0 37.2 Percent Non-Hispanic 72.1 69.0 62.8 Estimated Percent Jewish 53.2 46.4 37.8 Estimated Percent "Other" 21.1 24.5 26.7 *Remember that the actual number was 34,812, thirty-five more. ** "Other" means non-Hispanic and non-Jewish. The total is about 101.7% because about 600 voters are both Hispanic and Jewish, are counted in both groups, and hence lead to an overlap. Method of Analysis As in the earlier (September 1994) study, two methods of analysis are used: Ecological Regression Analysis and Homogeneous 3 Precinct Analysis. The Ecological Regression Analysis is based on precinct analyses, comparing the percentage of Hispanic voters in each precinct to the percentage of votes received by Hispanic candidates in each precinct. A complex statistical procedure predicts the "best fit" between these two variables. Precincts are weighted for size so that each precinct influences the statistical procedure according to its size. Homogeneous Precinct Analysis takes precincts which are heavily of one ethnic group, and looks at the votes for each candidate in these "ethnic" precincts. In Miami Beach, there are a cluster of precincts which are heavily non-Hispanic or "Anglo" (slightly over 80%), and hence these precincts can be analyzed. There are precincts which are majority Hispanic, and there are more precincts in which the majority of votes cast were Hispanic, but there are no precincts that are predominantly Hispanic. Hence, we cannot analyze "Most Hispanic" precincts. The "Most-Hispanic" results are presented on the following pages, along with the analyses of most-"Anglo" precincts, for information purposes only, Double checking ecological regression analysis and homogeneous precinct analysis against each other gives a good idea of whether the two techniques are close estimates of the actual voting resul ts. In the middle of each "Homogeneous Precinct Analysis" page, these two techniques are combined. As is shown, in each of these four elections the two sets of analysis were very close to each other in their estimates, suggesting that the analyses are very close estimates of reality. More details on these two methods can be found in the September 1994 report. Voter Turnout Rates Voting results depend not only on absolute numbers of registered votes, but on voting turnout ~ates for different groups of voters. Because individual voting data was used in this study, we can see voting turnout rates for different ethnic and age voting groups. The following results show that there were major differences in voting turnout for different ethnic groups in Miami Beach. Regardless of ethnicity, there also were strong age differences in voting rates, with middle-age and older voters voting at a much higher rate than younger voters. In looking at turnouts for ethnic-age groups, it is also important to note the sizes of the three age groups comprising each ethnic subgroup. A large number of young voters lowered the overall voting rate for each group, and the large turnout for older Hispanic voters for all Hispanic subgroups raised the overall turnouts for these subgroups. Out of a total of 34,777 registered voters, 10,689 voted, for a total turnout of 30.7%. Hispanic voters accounted for 37.2% of the registered voters, but because Hispanic voters had a higher voting turnout, they accounted for 42.6% of all votes cast. Because of the higher turnout, Hispanic voters accounted for the majority of the voters in 14 of the 31 precincts. (Precinct 26 no longer exists, but 14 voters still were listed under that precinct. Thus, the plots indicate 32 precincts visually, but prec~nct 26 counts 4 Table 1.

As shown in Table 1, the turnout varied by large amounts for different ethnic and age subgroups. The three largest subgroups of Hispanic voters are those from Cuba, Puerto Rico, and Colombia. Hence, these three groups are shown separately {for foreign-born only because national-origins heritage for United States-born Hispanic voters are not known} . Results also are shown for a sample of Jewish voters, by age groups, using the Distinctive Jewish Names Technique to obtain a sample. Results also are shown for a sample of non-Jewish, non-Hispanic voters by using a list of surnames. These are estimates, based on samples, but generally are basically accurate as estimates. Results Despite the federal judicial opinion regarding ethnically polarized voting in Miami Beach, this sociological and demographic analyis indicates statistically that ethnically polarized voting continues in Miami Beach. All four elections of November 1995 were characterized by ethnic polarization. The least polarization was in the mayor's election between Seymour Gelber and Andrew Delaplaine, in which there was no Hispanic candidate. The correlation between ethnicity and voting was .56, but the level of significance was .0008, suggesting that these ethnic differences would be found by chance only about eight times out of ten thousand. The most polarized voting was found in the election between Susan Gottlieb and Ada Llerandi, involving a non-Hispanic incumbent and a Hispanic challenger. The correlation was .93, and the level of significance was .0000, suggesting that these differences would be found by chance less than one time out of ten thousand. The election between Marty Shapiro and Matti Bower also involved a non-Hispanic incumbent and a Hispanic challenger. This race was less ethnically polarized than tbe election between Susan Gottlieb and Ada Llerandi, but the correlation was .79. While not as strong as the Gottlieb-Llerandi difference, this difference also was significant beyond the .0000 level, suggesting that these ethnic differences would be found by chance less than one time out of ten thousand. The vote on whether to change the name of Ocean Beach Park to Marjorie Stoneman Douglas Park also exhibited strong ethnic polarization. The correlation between ethnicity and voting was .83, significant beyond the .0000 level. This suggests that these ethnic voting patterns also would be found by chance less than one time in ten thousand. In summary, all four elections exhibited significant ethnic voting polarization. The results from least polarized to most polarized with ethnic registration-voting correlations are: Seymour Gelber and Andrew Delaplaine .56 Martin Shapiro and Matti Bower .79 Keep Same Name or Change Name of Park .83 Susan Gottlieb and Ada Llerandi .93 This summary is further supported visually by the findings at 6 the end of this report. The results for the two elections with Hispanic and non-Hispanic candidates are shown numerically in Appendix A, and graphically in Appendix B. On each graph, each point represents a precinct. The lines that connect the points show the percentage of voters who are either Hispanic or "Anglo." These graphs are not weighted for precinct size, but show how each candidate's vote varies (by precinct) from the line which shows the percentages of Hispanic or "Anglo" voters in each precinct. These graphs, without weighting and without any sophisticated statistical procedures, simply show how the votes received by these four candidates varies according to the ethnicity of the precincts. As seen from the graphs, as the number of Hispanic voters increases, the number of votes for Ada Llerandi and Matti Bower usually increase, and as the number of Anglo voters increases, the votes for Susan Gottlieb and Marty Shapiro usually increase. These graphs indicate that ethnic polarization did occur, to a degree that is obvious simply by looking at the graphs. References Lavender, Abraham D.

The correlation coefficient between Hispanic voters and favoring a name change to Majorie Stoneman Douglas was -.83, while the correlation between Hispanic voters and opposition to the name change was +.83. These correlation coefficients were significant beyond the .0000 level, indicating that these differences would be found by chance less than one time out of ten thousand. 18 PLOT OF ELECTION ON WHETHER TO KEEP NAME AS OCEAN BEACH PARK OR CHANGE NAME TO MARJORIE STONEMAN DOUGLAS PARK Based on Bivariate Ecological Regression Analysis --Each Square Represents a Precinct --Vertical axis (up and down) = percent of votes received by "Yes, Change Name" (first choice on ballot) --Horizontal axis (left to right) Hispanic percent of voters who are --Conclusion: As the percentage of Hispanic voters increased, the percentage of "Yes, Change Name" votes decreased 100 " .., . . . . . . . . .. . . . - 25 o o Z5 50 75 IlO 19 1995 PARK RENAMING HOMOGENEOUS PRECINCT ANALYSIS RESULTS KEEP SAME NAME OR CHANGE NAME MOST "ANGLO" PRECINCTS Precincts included in analysis: 23, 24, 25, 27, 28, 30 OF TOTAL VOTES CAST, PERCENT CAST BY "ANGLOS": 81.3% OF TOTAL VOTES CAST, PERCENT CAST BY HISPANICS: 18.7% TOTAL VOTES COUNTED 2,140 Ballot Choices: Number of Votes % of Votes No, Keep Name as Ocean Beach Park Yes, Change Name to M.S. Douglas 949 1,191 44.3 55.7 COMPARISON OF ECOLOGICAL REGRESSION ANALYSIS AND HOMOGENEOUS PRECINCT ANALYSIS (USING MOST "ANGLO" PRECINCTS): Of the 2,140 votes counted in this cluster of precincts, 18.7% (400) were cast by Hispanics and 81.3% (1,740) were cast by non- Hispanics. The regression analysis suggested that "Yes, Change Name" received 30.7% of the Hispanic votes (400 X 30.7% = 123 votes) and 62.5% of the non-Hispanic votes (1,740 X 62.5% = 1,087 votes). The Hispanic 123 and the non-Hispanic 1,087 totals 1,210. The actual number of votes received was 1,191, suggesting that the estimate obtained by the regression analysis is very close to the actual number received. Because there were only two choices, the numbers for "No, Keep Same Name" are the reverse of these and hence are not computed.
