Organizations in this bracket typically operate with a small permanent staff, project-based program structures, and modest reserves. Program-spending efficiency is strong: 80% of total expenses flow to program activities, above the 75% benchmark most third-party charity raters use.

Revenue has grown meaningfully across the five-year filing history — a sign of expanding donor base, new grants, or scaling programs. Houston Museum Of Natural Science reported $82.1M in 2023, up notably from the start of the window. CEO compensation is reported as zero in the filing — typical for nonprofits where the chief executive is paid through a related entity (parent system, university, or foundation) rather than the filing organization itself, or for small organizations whose chief is a volunteer or board member. Houston Museum Of Natural Science sits in the cultural-nonprofit sector (Arts, Culture & Humanities). Museum, performing-arts, and cultural organizations carry distinctive financial patterns — earned revenue from ticket sales and admissions, plus a heavy reliance on endowment income and major donor cycles.
