The U.S. Department of Agriculture (USDA) reports data on cigar sales in two categories: little cigars (weighing less than 3 lbs. per thousand) and large cigars and cigarillos (weighing more than 10 lbs. per thousand). A rise in the sales of little cigars in recent years is a cause for concern. The capacious second category could be obscuring the growth of sales in cigarillos.
Trends in cigar use were analyzed in May 2007 using (1) the standard USDA two-level system and (2) data from the Maxwell Report that provides information on cigarillos as a separate category. The intercorrelations among cigar use trends in the three areas were also explored.
From 1993 to 2006, unit sales of little cigars increased from 37% to 47% of the cigar market, cigarillos increased from 25% to 32%, and large cigars dropped from 37% to 22%. From 1976 to 2006, cigarillo sales were strongly related to sales of little cigars (r=0.93; 95% CI=0.86-0.97), while sales of large cigars and cigarillos were modestly related (r=0.42; 95% CI=0.08-0.57).
Analyses show strong correlations between cigarillo and little cigar sales and argue for more detailed reporting of cigar sales as a function of cigar size. Tobacco surveillance should at minimum be watching the same trends as the tobacco industry. The sales of little cigars, cigarillos, and large cigars should be monitored, and the measuring of cigarillo sales in 3-5 subcategories according to size is encouraged.
美国农业部（USDA）报告两类雪茄销售数据：小雪茄（每千支重量不足3磅）以及大雪茄和小雪茄烟（每千支重量超过10磅）。近年来小雪茄销量上升令人担忧。范围宽泛的第二类可能掩盖了小雪茄烟销量的增长。
2007年5月，利用（1）美国农业部标准两级系统和（2）马克斯韦尔报告提供的将小雪茄烟作为单独类别的数据，分析了雪茄使用趋势。还探讨了这三个领域雪茄使用趋势之间的相互关系。
从1993年到2006年，小雪茄的单位销量从雪茄市场的37%增至47%，小雪茄烟从25%增至32%，大雪茄从37%降至22%。从1976年到2006年，小雪茄烟销量与小雪茄销量密切相关（r=0.93；95%置信区间=0.86 - 0.97），而大雪茄和小雪茄烟销量的相关性一般（r=0.42；95%置信区间=0.08 - 0.57）。
分析表明小雪茄烟和小雪茄销量之间存在强相关性，并主张根据雪茄尺寸更详细地报告雪茄销售情况。烟草监测至少应关注与烟草行业相同的趋势。应监测小雪茄、小雪茄烟和大雪茄的销量，并鼓励根据尺寸将小雪茄烟销量细分为3 - 5个类别进行测量。
