Custom Merch for Events in Washington, DC
Merch Mob makes attendee and souvenir tees, staff, crew and security shirts, and volunteer shirts for events in Washington, DC, at its shop in Montclair, CA, and ships them to Washington. Washington's 18-to-34 age group makes up 32% of residents, above the US rate of 23% (Census ACS, 2020-2024), so attendee merch should look like something worth wearing again, with the poster art front and center.
Washington by the numbers
Washington's population has held steady since 2020, at 693,645 residents (Census estimates).
District of Columbia has 48 event promoters (performing arts, sports and similar events) with paid employees (Census County Business Patterns, 2023). That is 0.69 for every 10,000 residents, above the national figure of 0.27. 73% of them employ fewer than 10 people. The count is up 17% from 41 in 2018.
That counts promoters with a payroll; one-off events run by volunteers or venues are not in it.
District of Columbia has one event promoter for every 14,450 residents. Of the 60 counties behind these pages for events, District of Columbia has the 5th-most event promoters (performing arts, sports and similar events) per resident.

What Washington's weather means for events
Winter in Washington bottoms out at an average high of 45°F in January, so cold-season events need hoodies and long sleeves on the table, and staff need a layer once the sun goes down. The tee season is short, May to September at a 70°F average high or more, so outdoor festivals cluster there, and staff tee orders should be settled well before it starts. Order fleece for fall events so it arrives before November, the month average highs fall below 65°F, and put staff in long sleeves for early load-ins from then on. Snow is occasional, about 14 inches a year, so a winter date needs a weather-call deadline and a backup day. Cold nights are common, with the low at 32°F or below on about 60 nights a year, so an event that runs into the evening needs a warm staff layer for the last hours, and beanies belong next to the hoodies on the table.
