Data from California were used to explore the role of gender in early markets for electric vehicles (EVs). Differences and similarities between women and men in their prospective interest in EVs were analyzed and placed in context with observed motor vehicle and EV sales in California. Similar, contemporaneous data from 12 other states have not been similarly analyzed. This research analyzes these other state data with the same emphasis on gender. The other states represent a spectrum of EV policy and marketing contexts. No other state had EV sales as high as in California. Some had prospective interest as high as in California but in most awareness, knowledge, and prospective interest were lower. Consumers in all states were eligible for federal tax credits, but no other state had as generous state incentives as did California and most had none. The research addresses two questions. First is a matter of repeatability of results: are differences such as those in California between female and male respondents found in samples from other states? Second, do any such differences vary by policy and market context? Tests of repeatability and robustness across contexts inform actions required to assure gender-equity in participation in EV markets.
