This market resolves YES if share of households headed by a cohabitating couple and households headed by a married couple in the US 2030 Census are greater than one half.
The Census Bureau has a brief description of these results for 2020 (see figure 3). In 2020 there were about 126.9 million households. Of these 58.7 million were headed by a married, while 8.8 million were headed by a cohabitating couple.
The resolution date was chosen based on timing that the previous Census article was released. I am open to changing the resolution date if there is good reason to belief the results will be released publicly at an earlier date.
Title and description seem to be in conflict: "majority" coupled in title vs "less than or equal to one half" (i.e. minority) coupled in description. Which is it? Or am I misreading?
