## 10 Discussion
* Testing and Auditing: Conduct regular testing, simulations, and auditing of the census blockchain system to identify weaknesses and make continuous improvements to the system and procedures. * Individual Ownership and Access: Give individuals access to their own census records and a means to report errors or changes. This helps engage individuals and keeps the data more accurate. On the other hand, if we talk about specific marginalized groups, a few effective measures can ensure that these groups are counted during the census process. * Targeted Outreach: Conduct targeted outreach campaigns specifically focused on marginalized groups like homeless populations, migrants, refugees, indigenous groups, etc. This could include on-the-ground outreach workers, partnerships with local nonprofits and community groups, and multilingual messaging. * Accommodate Diverse Living Situations: The census should be designed to accommodate people with diverse living situations, including those without traditional housing, stable addresses, or documentation. Allow options to report temporary addresses, cross-streets, or describe locations, and accept reports from shelter administrators or outreach workers. * Incentivize Participation: Provide incentives for marginalized groups to participate in the census, such as access to essential services, food assistance, healthcare, cash payments or credits, etc. This can help overcome distrust or a lack of motivation to engage with the census. * Accommodate Disabilities and Limitations: The census procedure and forms should accommodate individuals with visual impairments, learning disabilities, limited literacy, or other issues that could deter participation. This could include braille, large-print and audio questionnaires, a simplified census form, and census workers with relevant training. * Build Trust and Reassure Privacy: Conduct education campaigns to build trust in the census process and reassure individuals, especially marginalized groups, that their data will be kept private and secure and will not be used against them. Transparency about data usage and consent policies can help build confidence. * Partner with Advocacy Groups: Census agencies should work closely with advocacy groups representing marginalized communities. They can provide input into census design, help promote participation, and reassure their communities that the census is necessary and safe to engage with. * Provide Census Surveyors with Diversity Training: Require census takers and outreach workers to complete diversity and inclusion training so they have a better understanding of the barriers and issues faced by marginalized groups. They will be better equipped to effectively conduct outreach and properly count these populations. * Follow Up on Undercounted Areas: Analyze census results to identify geographic areas or communities that appear to be undercounted. Then, conduct follow-up outreach to count missing individuals and work to determine the causes for the undercounting so the next census can be improved. * Accept the Self-reporting of Demographics: Allow individuals to self-report demographic information, like ethnicity, tribe, disability status, income, etc., rather than having census takers assign categories. This will result in more accurate counts, especially for marginalized groups. These are some of the critical ways in which a census can help ensure that even the most marginalized groups in society are correctly counted. A census has a better chance of achieving a complete count with targeted outreaches, accommodations, trust-building practices, partnerships with advocates, and follow-ups on undercounts. From a controversial point of view, the following question can be raised: why use blockchain if these problems can be resolved or improved in a centralized system? Building a transparent and secure system for a census using centralized database and technologies is feasible, but it comes with some inherent challenges and trade-offs compared to a blockchain-based system.
