This study investigates the complex relationship between the emphasis on racial and ethnic diversity in economic development marketing and the availability of grant or loan programmes for immigrant entrepreneurs. Utilizing a comprehensive survey conducted in collaboration with the International City/County Management Association and Cornell University, the research analyses responses from chief administrative officers across U.S municipalities. The study employs quantitative analysis to examine the correlation between diversity-focused marketing strategies and the existence of financial support mechanisms for immigrant entrepreneurs. Key findings reveal a statistically significant association between the emphasis on diversity in marketing and the presence of support programmes. However, the study highlights the discrepancy between marketing claims and actual support available to immigrant entrepreneurs. The policy implications suggest a need for authentic integration of diversity in both marketing and program implementation, emphasising the role of tangible support mechanisms. The findings underline the necessity of holistic and inclusive economic development strategies that align promotional efforts with practical support for immigrant entrepreneurs.
