Data Cleaning and Integration

At 1930 Research LLC, we excel in bringing order and clarity to the most challenging datasets—including Big Data from tens to hundreds of millions of rows. We tackle all types of issues including missing data, inconsistent documentation, or shifting reporting conventions to ensure your data is accurate, reliable, and ready to support sound decision-making.

Our services include:

  • Identifying Missing Data: Filling gaps to restore completeness and accuracy.

  • Standardizing Values: Resolving inconsistencies to create clean, uniform datasets.

  • Creating Cohesive Categories: Organizing complex data into meaningful, practical structures that enhance usability.

  • Merging Data Sources: Combining disparate datasets to provide a comprehensive view of trends and patterns.

We also aggregate data to meaningful units—such as police districts, years, or other actionable categories—delivering insights that allow you to allocate resources effectively and address challenges.

If any data falls short of reliability, we let you know upfront, safeguarding your organization from costly mistakes and poor decision-making. Not all data are suitable for every project, and we prioritize your success by providing honest, ethical assessments. Our commitment to trustworthiness means we only pursue projects where the data can deliver reliable and meaningful results, ensuring your outcomes are both accurate and impactful.

Visualization and Reporting

Interpreting crime data is challenging, and poorly designed visualizations can mislead even the most experienced professionals. At 1930 Research LLC, we specialize in creating clear, accurate graphs, maps, and tables that make data accessible, meaningful, and actionable. Our goal is to tell the data’s story accurately and directly, ensuring insights are conveyed without distortion or misrepresentation.

Our deep understanding of the criminal justice system, including our team’s advisory work with the FBI, equips us to report data with the proper context and precision it demands. This unique expertise ensures that our visualizations and reports not only present data clearly but also reflect its underlying realities, supporting informed decision-making.

We also create detailed, well-documented reports that plainly explain essential caveats to data interpretation. Our team’s work has been used in government publications, legal proceedings, and academic manuscripts, providing clear, reliable insights in critical contexts where accuracy is paramount.

Automation

For many organizations, recreating reports—whether monthly, yearly, or with slight variations like offense types or geographic areas—can drain valuable time and resources better spent on strategy and decision-making. At 1930 Research LLC, we simplify this process by automating reporting workflows, saving time and enabling your team to focus on achieving impactful goals.

We develop custom R code to generate recurring reports with consistent, accurate outputs, adapting to adjustments as long as your data structure remains consistent. By providing the R code, we ensure your organization retains full independence to generate these reports indefinitely without relying on external support.

Automation not only saves time but also enhances accuracy, reduces errors, and optimizes resources. With 1930 Research LLC, your team can focus on the big picture—not redoing the same busywork again and again.

Analysis

Crime data presents unique challenges, from navigating complex data structures to accounting for context and limitations. At 1930 Research LLC, we bring the expertise and practical understanding needed to interpret crime data correctly, ensuring that every analysis supports sound, informed decisions.

Poorly conducted research isn’t just costly—it can lead to flawed conclusions that endanger communities, misinform the public, and undermine the effectiveness of law enforcement. Our commitment to precision and reliability ensures that the insights we deliver are not only actionable but also grounded in careful, context-aware analysis that minimizes risk and maximizes impact.

Our team offers a full range of analytical services:
