Determining the exact number of attendees at any protest can be challenging, and the "No Kings" protest is no exception. Various factors influence the accuracy of these estimates, including the size and location of the event, the duration, and the methods used to count participants.

Challenges in Estimating Crowd Size

  • Fluid Movement: Protests are dynamic events. People arrive and leave throughout the duration, making it difficult to get a precise count at any single moment.
  • Multiple Entrances: If the protest spans a large area with many entry points, accurately tracking everyone becomes nearly impossible.
  • Varied Estimators: Different organizations and media outlets may use different methodologies, leading to a wide range of reported numbers.

Methods Used to Estimate Crowd Size

Several methods are commonly employed to estimate crowd size:

  1. Jacobs’ Method: This involves dividing the crowd into sections, estimating the density of people in each section, and then multiplying by the area of each section. Density is typically categorized as:
    • Sparse: One person per 10 square feet.
    • Dense: One person per 4.5 square feet.
    • Very Dense: One person per 2.5 square feet.
  2. Official Permits: If the protest organizers obtained a permit, the permitted number can provide an upper bound, though actual attendance may vary.
  3. Aerial Photography: Analyzing photos taken from above can give a visual estimate of the crowd's size, which can then be quantified using image analysis techniques.
  4. Expert Estimates: Crowd science experts can provide estimates based on their experience and available data, often combining several methods.

Factors Influencing Attendance

  • Public Sentiment: High public interest in the cause can drive larger attendance.
  • Media Coverage: Significant media attention can attract more people to the protest.
  • Location and Accessibility: A central, easily accessible location tends to draw more participants.
  • Timing: Weekends or holidays typically see higher turnout than weekdays.

Where to Find Estimates

  • News Reports: Major news outlets often provide estimates, but it's essential to compare multiple sources.
  • Social Media: Platforms like Twitter and Facebook can offer anecdotal evidence and user-generated estimates, though these may not be reliable.
  • Organizers' Claims: Protest organizers often release their own estimates, which may be higher than neutral assessments.

Ultimately, determining the exact number of people at the "No Kings" protest requires a comprehensive analysis of available data, keeping in mind the inherent challenges in crowd estimation. Comparing multiple sources and methodologies will provide a more informed understanding of the event's scale.
