Overall since 1879 more than seventy percent of proposed amendments have been ratified. But since the 1960s, as Texas began to modernize, amendment activity has risen sharply. More than sixty-one percent of all amendment proposals have been made since 1960. From 1879 to 1959 the legislature proposed 234 amendments, on average 5.7 each session. Of these the public ratified just more than sixty-one percent.
