<p>Over the past 50&#xa0;years there have been significant changes in the political environment that may have affected parents’ ability to socialize their children into similar political attitudes and beliefs. This paper investigates the effects of greater attitude constraint among parents on how successful parents are at transmitting their political values to their offspring. Using data from the Youth-Parent Socialization Study I demonstrate that the greater the extent to which a parent’s political attitudes are ideologically constrained, the more likely it is that their child adopts similar political beliefs and attitudes, even after controlling for a multitude of other explanations. This may suggest that an increase of ideological constraint among some segments of the population has led to increased success at passing along their political attitudes to their children, while other segments of the population that have not become more ideologically constrained have not experienced any such increase in success.</p>
